The thing that surprises me the most about this entire episode is that Alec is not the kind of person to read his owner's manual front to back within the first 30 days of buying his car.
I read manuals for cars I don’t even own, but am really interested in. It’s a good way to know all the useful little features the cars/devices have. Side note- I especially hate how so many companies are making the goddamn user manuals web-only, the whole point of a manual is you don’t need a network connection to look something up. I miss pdf manuals. Edit to add clarity- They don’t even have an option to download a pdf version, it’s just a link for the online manual. It’s much more clumbersome to jump back and forth between sections
As an engineer I spend the majority of my time reading the manual, or more formally datasheet. So I feel like it's more the first than the last resort.
Why 8:50? The hood covering the blades gives you quite a bit more efficiency and therefore range, ist smart design. And the button to service the blades is literally right in the service menu in the car, couldn’t be much easier. The decision to not use a rain sensor however is borderline stupid, wipers don’t work well on Teslas now since 7 years and counting
@@PopsGG “To save money”?? And that’s pathetic excuse from Tesla. For a car that’s $60-130k?? More reasons why Tesla should never be considered an “luxury” brand. What other amenities are they missing?
I know you do the low effort videos for yourself, but I would like to remind you, we all watched an hour long video about dishwashers and loved it. I still, to this day, get the hot water flowing to my sink before starting the dishwasher add soap on the door because it doesn't have a place for first stage soap. We love your shit, bro.
Same. I even made my husband watch it so when he starts the dishwasher, he does the same! Now if only I can convince him to pay attention to the rinse aid getting low...
Dishwasher video actually changed my life. I’m sure my machine isn’t very high quality but it gets caked on food off all of my dishes so good now that I’m using it properly.
You do realize how much work even a short video like this takes? This isn’t tiktok he doesn’t use a selfie cam and record himself love for 11 minutes then say he’s done for the day. This video even though short probably took weeks of not months to put together if he did it himself. From filing to editing, to audio mixing, graphics that all takes a lot of time if you do it yourself. Not to mention the UA-cam algorithm is probably top of his mind. While it’s not exactly known how it works shorter videos are far more likely to be recommended because they are more likely to be watched to completion which Netflix has said is the ONLY criteria they care about so it would make sense UA-cam follows a similar format since they do similar medium. So I praise him for making such a high quality video especially if all of it was done by himself. And if you want longer videos there a simple solution give him 60,000 every year so he can afford an editor so he has more free time to make longer videos.
@@erebostd first auto wipers were sold in 1970, but also pulse oximeters were merely commercialized in 72-75 - the technique was invented in 1937! it just took a while for technology to get them small / accurate / cheap enough to make it into health care at scale.
"Look, I get it wet, and the car wipes! But two can play at that game-" then using a screen whipe as a transition between frames. Is exactly the kind of joke I love getting blindsighted by between detailed information in a presentable manner, and truely midwestern levels of snark.
I had two very nice surprises recently after buying a very cheap Citroën from 1998. First, it has a rain sensor. And second, It´s by far the best working rain sensor i have ever seen. It never gets confused or start when it´s dry or forget to wipe when it´s wet. It´s 100% perfect all the time. And they did that in 1998!
@@Filip_Phreriks They are so brilliant that they had solutions to even non-existing problems. One of my favorites is that the magnificent DS had real-time self adjusting height correction on the headlights....on a car that also has self leveling suspension. I mean, it´s a good idea for headlights to not jump up and down when you go over bumps. But then again, I have yet to see the DS jump at all on any bumps. You can actually take a speed bump way too fast in a DS with a glass of water on the dash without even upsetting the water. Gotta love them...
As a software engineer, thank you for spreading the gospel off RTFM. As a sidenote, the people who need to be told to RTFM also seem to be the people who don't write any manuals for the stuff _they_ make, or don't bother describing 80% of the functionality in it. Not sure what is more frustrating. Telling people to RTFM or finding out there is no FM to R.
Ha! I think that might be referring to parking outside during freezing rain. You have to put your wipers up, or they're freeze to the bottom of the windshield and take forever to thaw.
That's one thing I love about my Tesla: Wiper Service Mode is just right there in the Service menu. Easy to find. Easy to use. Easy to disable when you're done swapping out the wiper blades.
@@coredumperror but you have to admit, Vision based auto wipers is still crap. I'd take a proper rain sensor over slightly easier blade replacement any day.
@@R.Daneel In my experience, owner's manuals use the most obscure terms for normal things making it hard to lookup anything. Example: Let's lookup turn signal replacement and eventually stumble across "intermittent directional lamp disassembly"
Well, tesla isn't the only car company trying to make the cabin look more futuristic by moving controls into the infotainment system, or using touch surface buttons... it's also cheaper than actual knobs and buttons... But it's so annoying to the driver, especially if that driver is old enough to have the muscle memory. It's all good and convenient with cars that try to help you driving. But there will be cases where it's nice to be able to override the fancy stuff, and preferably without removing your eyes from traffic. Leave my gear selector alone, let me manually override lights, blinkers and wipers. And give me a knob for volume and climate control. Let me engage, disengage and adjust cruise control without lifting a hand from the steering wheel. I also like how Hyundai use paddles to adjust regeneration and how Audi lets you change drive mode while driving, so you can switch to ECO when you enter a town, or you see the battery level disappearing faster than you planned. Don't make me pull over so I can adjust everything for the further journey in the infotainment system. And don't try to make me try voice control... as a non-native English speaker I'm sure that I pronounce some words incorrectly, and the Danish voice recognition isn't as well trained as the English one. When that rant is out, I'll agree that it looks nice and sleek with all that touch and simplified controls... it's just not very practical.
@@BenjaminVestergaardI think he’s more alluding to the lack of auto-wipe sensors in current Tesla models, since they moved to a pure camera implementation that, frankly, is just awful and doesn’t work. All to save a few bucks per car.
@@mobibobobobobobobvobobo well, tesla also made away with the radar and ultrasound sensors... all camera based now... I can't imagine that working very well for very long during a Danish winter if we have snow, because we spread salt on slippery roads. It creates a nice sticky sleet along the edge of the road, and during snowfall, that stuff builds up and you need to use sprinklers on your windscreen for it to remain clear. I've experienced that sleet build up to get so bad that the radar didn't even work after an hour on the highway, and the camera based lane assist was not exactly reliable either. That was a Hyundai I think. Edit: but I'm sure that Teslas all-camera system works pretty well in sunny California.
I haven't seen your channel for a while but I wanted to say I can tell you've been working on your fitness and you look good! I know as men we don't hear compliments often, so I wanted you to know it's visible and you're doing a great job
Alex, we've been saying RTFM since at least the 1980's. I've gone through the manual for every car I ever owned and always find something new, unexpected, and useful there. You found your wiper hack. On my 2017 car I found how to get into and start the car even if the battery in the key fob dies.
You have no idea how amazing this video is for me. One day, I wanted to know how this worked on my car, but when I googled “how do rain sensing wipers work” I just kept getting pointed to manufacturer webpages that just say “automatically detects rain and activates wipers” without anything saying HOW it detects rain. It’s bothered me ever since. Thank you!
Ah yes. Google is completely useless these days. ChatGPT performs quite a bit better, but is still somewhat vague about the specifics. Nothing beats a well-made video like this where someone did some actual effort, in spite of the Effortstat™.
this is why i love gen AI and AI search engines, I just asked copilot which answered it perfectly. it works so well for those random questions. but always keep in mind it can just make up stuff, so trust but verify
I once had the privilege of working along side a Technical Author and he worked really hard to create a useable, easy to understand users' manual. He did comment that the manual would only be as good as the information that we (the Engineering Team) provided and the amount of time we were prepared to spend answering his questions. It always struck me as a bit of a shame that he didn't get to put his name on the manual that the customers got to read.
When I was working as a techwriter, there was a spectrum. Some departments (and specific engineers) were awesome to work with, and some would only give you single word answers after being bugged for weeks. The teams that worked with us had amazing documentation, frequently modified their product as a result of our conversations, and often learned for the first time about related things that other teams were doing. The teams that didn't engage had minimal (and sometimes incorrect) documentation, and did not get those abstract residual benefits of being in the hive mind of the techwriting department. EXCEPT that one time when there was something very complicated to be documented, the engineer was far in the "difficult" corner. I wound up having to both run and read his code to get answers to my questions. Surprise: I found some significant bugs by asking questions like "what is this interface" and what happens if you do these two things at the same time"? Communicating about your work benefits everybody, especially you.
I love this episode. I especially love pointing out the technology connection between electric ovens and automatic rain sensors. I love the way you explain stuff
No! You're wrong! Alec shouldn't be allowed to use that doodad, he should make long videos. This video would have been better if he'd bought 2 cars, just to dismantle 1 to get to the components. (Isn't sarcasm fun...)
I have a brand new refreshed model 3, and I will happily admit that they are currently absolutely garbage. There are rumors of an upcoming update to improve them, but I am not holding my breath for it. They trigger at the appropriate time for me, but often at the wrong speed (light rain, and they are going crazy, heavy rain, and they are too slow). The one remark I will commend them on, is that they are easily controller via the buttons on the steering wheel in my case.
Thank You.....As a life-long Electronic/ Mechanical/ repairman & Inventor This is a very rare occasion where I totally learned something I knew nothing at all about....Very satisfying... Thank You
I did. I read the whole manual. I also read all the announcements my work makes, the instructions for any electronic item I've purchased (even if it's just a basic toaster), and the newsletter that my local council puts out. Some days I'm almost convinced I'm not autistic. Until the next time I do something others consider out of the ordinary. I like knowing things! 😅 Which is why I like your videos, they're always fascinating.
I was presented a car for my 60th birthday couple of weeks ago, and for the first time in my life I did the right thing - I read the manual before starting to use the car. 😂 And I found it a very useful thing to do. So, it's never too late to start.
Thank you for explaining how it detects wetness. I couldn't find that answer so clear as you told it. . Also, I now understand why sometimes when I start up the car in light rain, it refuses to wipe. I always leave it on "auto", and now I know it's because of the 'dry calibration'.
@@reinhard8053 Yeah. I was expecting "but through the magic of buying 2 of them" with some car part whipped out from under the desk throughout the video, and left a bit disappointed.
I've always been curious about how these things work. It's so cool that it's such a simple mechanism. I own a Kona Highlander EV, and as a bonus I now don't need to look up how to change the wiper blades in the manual. Thanks Technology Connections!
Known this since the '90s (thanks, highschool physics professor) , though just now noticed a UA-cam video about it. No, I haven't searched. Top job, lad!
@@Jedocesque Some might see this as a joke, but aircraft carriers do have window wipers, but unlike many ships, it's all around the tower as they need to see everything on the deck, not just where they are going.
@@Jedocesque As I understand it, changing the wipers on an aircraft carrier is easy. Mention the situation to a Petty Officer and he'll tell an E-2 to do it.
I worked in the automotive glass supply chain in the early 2010s. Sensors like this drove me nuts because the different combinations of them meant that there were nearly *30* different windshield variants for different cars, depending on which package the owner had.
@@coredumperrorHe's implying he doesn't care about auto wipers, probably because his don't work well anyway so he just uses manual. Tldr, that's the joke
I used to deliver parts to a used car dealership's garage. They bought a Tesla to flip once and swore they'll never touch them again because if you replace the windshield you have to pay Tesla a couple thousand dollars to send somebody out to program the windshield.
Thank you thank you! I had an intuition very close to the solution but never bothered looking up how they actually work. This has satisfied my itch to know about this for years!
I have had my current car for like 4 years, and I just discovered this setting the other day (I'm bad about manuals), so I was wondering how it works, and lo and behold! It's like my car knew this video was coming, and inspired me so I'd be ready. So far, I've found it's mostly ideal for the kind of light drizzle that's not enough to fully turn the wipers on, but enough that one-off wipes aren't cutting it. That covers a surprising amount of the rain in this area
As a Tesla owner, I fully appreciate the shade being thrown at "any organization in particular". I do, however, have a wiper service button that is easily findable, so there's that...
@@ashliehiggins Sure, if you have any idea how to do it. Alec specifically bashed his Ioniq 5 for hiding the method of turning on wiper service mode in the manual. Teslas put that method right there in the Service menu.
@@coredumperror You're supposed to read the manual before operating the car, on two of my cars I found it out accidently and now test if every car I drive does it.
I love that a proper RTFM message was given at the end. Also props for index of refraction hacks car industry. Sometimes the smartest people show up in the weirdest of places to solve the most banal of issues. We already have the capacity to turn on our wipers, have for decades. But someone somewhere thought to themselves, "Ya know, I bet I could take $0.50 in parts from our bulk purchases and make a thing that can turn on the wipers automatically..."
let's be real here, that person probably said automagically, because the people who are the highly-educated types rarely think of the elegantly simple solutions.
@@CrisperPoet You've never been in a room full of engineers, have you? They absolutely LOATHE marketing speak and will openly play "buzzword bingo" to mock them. People who are highly STEM educated, and seasoned in their field, absolutely obsess over making solutions as elegant and simple as possible. It's the social "science", management, marketing and economics people who think in fluffy, emotional and fictitious terms.
I have a Ford Endura here in Australia, aka your Ford Edge. Went to change the blades and I could just turn the arm and it turned super easy and not connected to a seperate motor with levers, very weird. Turns out each wiper has its own motor with encoders so the onboard module tells each motor when to wipe, how fast and how far. Very clever and complicated. Saves engine bay space as well.
I’ve worked in technical support for many years, from water heaters to security systems. 25% of my job is reading the manual for people who can’t be bothered. We sold you the info when we sold you the product, man!
For some things I will read the manual before I buy the product. This often clears up the information that the companies marketing department provides. Usually there are a few things that marketing/ advertisements says that are slightly misleading.
I was helping someone put music on a USB flash drive to use in a Lexus recently, and the manual actually had an incredible amount of detail about the supported size, filesystems, codecs, etc. Car manuals really are helpful!
@@bobmahnamahknob That's not entirely a given in the age of cheap Chinese products with Google Translated pieces of paper intended to give the illusion of a useful manual.
@@bobmahnamahknob A lot of stuff doesn't come with useful manuals any more, especially when it comes to computer systems, documentation is a lost art.
Loved the video and the explanation. Not at all how I thought the rain sensor worked. Thanks! The Beta videocassette sleeve certainly brought back fond memories! Hahaha
My 2005 Buick LeSabre had automatic wipers and I'm surprised it was on such a relatively old vehicle and not any of the newer ones I've had since. It also had a sensitivity adjustment on the stalk which was interesting. Useful too because sometimes it would get a bit too sensitive and trigger when sudden darkness was encountered, like under an overpass, tunnel, etc. It worked really well overall and I rarely if ever had to use the manual modes
Thank you so much for covering this, when I tried to look up how one worked, the best answer I could find in the internet was “it works by sensing rain”. Gee thanks.
Oh my god Alec, you literally helped me save a loooot of time and money by publishing that video! I have had an issue with my Renault Zoe R135 automatic windshield wiper sensor from since I got it (used). By taking a photo of the sensor I was immediately able to see that the sensor is fine, but that the optical gel is nearly completely gone, probably from a shady windshield replacement in the past. It seems to be fairly easy to buy a new gel pad and replace it by my own, so thanks both for the (as always) excellent in depth view and explanation of this sensor, and for saving me quite a few bucks! EDIT: After thinking about the solutions and looking at the photos I took, I realized that it could be that the sensor was not completely clipped in. After disassembling the plastic housing around the rear view mirror, I was greeted with a semi-clipped in sensor. Reattaching the other side re-sealed the gel without any bubble, and the sensor seems to function as normal! I'll just need to see with the next rain.
We have this problem with brand new cars. If you get a tiny speck of dirt on that gel at all, or like a fingerprint or if you drop it on the ground and then try to install it it will not work. Source: I put this piece on cars all day.
I was also wondering how windshield replacement was going to affect this. I'm sure it's not just a "shady" replacement company, but any company as getting the right kind of gel and the correct amount, must be tricky.
@@BryTee You're close, they come with the little gel layer already on them and a little plastic cap covering it that you must carefully remove without touching the gel. Ours are manufactured by hella, and we get them I think for $12 a piece. When we get one that doesn't work they just swap the whole sensor out. But I bet at the dealer these things are over $100.
@@JasonHenderson @BryTee In this case I'm happy to report that the sensor was just not clipped in on one side! I have to assume that the technician who installed the sensor didn't clipped it in fully and that over time it detached. The gel was apparently undamaged as I tested the sensor and everything seems to work fine! No bubble or anything after checking with a photo.
I was a technical author, and Alex's conversion to RTFM was music to my ears. From time to time a friend calls me because they can't install or fix something. I go round, ask for the manual, consult the manual and install or fix the equipment.

I know a guy who basically made this a second job. He advertised himself as a maintenance guy for any appliance in people's home, had no qualification for it, but he just got the manual for anything people brought to him and used it to "repair" them for a fee. I put repair in quotes because sometimes it was just people doing proper maintenance on their stuff because they didn't know they had to maintain itXD
@I don't think of this as a scam, he's actually earning his keep providing a necessary service. As someone who used to earn my living as a "field engineer" (highfalutin term for repairman with a car). From many years of experience I can assure you that 99 times out of 100 It isn't the device that needs repairing, it's the customer.
Being an IT specialist opened my eyes to reading manuals/documentation. As a kid/teen I loved to dig around and test out different stuff an felt like a genius when I figured it out all by myself, but nowadays I understand that that's actually a stupid approach, where you're just stumbling around in the dark trying random things, only to invent the wheel again after hours of trial and error when you could have simply read some instructions and built your wheel in a few minutes. And that's just in the best case! Quite often you will not achieve anything, or you mess up some settings and don't know how to revert it back, or in the worst case, you end up breaking something that may or not be repairable. It's really mind boggling how people always think not reading the manual would be the smart thing to do! 🤦 I'm seeing this confirmed right now with my switch from Windows 10 to Linux on my gaming PC that I've made 10 days ago. I've always been using Windows, but got really frustrated with Microsoft's shift away from a user-focused UX towards pushing their own services and third party programs/services on a commission onto the user, regardless of the user's preference settings. Because of that, I've been considering jumping OS for years, but dreaded the experience of having to re-learn using a computer from the ground up on the new OS. I tried Linux a few years ago, tried to get everything running on my own and it was horrible, so I went back to Windows. This time though, I religiously stick to instructions from how-to's and forum posts and it's been nothing but smooth sailing and I can't even imagine going back to Windows anymore! Granted, there are other factors at play, like choosing a flavor of good old, well supported Ubuntu, rather than a fairly new distro that was Arch-based if I recall correctly and the fact that software and game compatibility (as well as the availability of good online instructions, I reckon) has improved tremendously since then, but sticking to existing guides/solutions, rather than just reading the basics of what I'm trying to do and then attempting to make my own, highly custom solution (with barely any knowledge of the OS) definitely plays a big part in the switch to Linux being a complete success this time!
@@LRM12o8 man [whatever] is a beautiful thing. I remember once having trouble on a Win10 machine connecting to the internet, and the help button in the settings page literally opened an Edge tab with a Bing search for "Windows 10 help connecting to the internet" (or similar terms). I couldn't help but laugh, it was so bad.
I was impressed years ago when I got onto a unix system (real unix, as linux hadn't come along at that point) and was poking at the manual when a thought occurred to me. I typed "man man" and sure enough, some elder nerd had taken the time to explain how to use the user's manual! Bliss. :-)
I read the manuals of all the things I buy. So... I think everyone should do it too. I always learn a lot of new things about my cars. 😊 loved the video.
Loved everything about your video. You explained the problem well and made it easy to understand even for non technical users. And I loved the vibe, kind of like from 80’s or so. Needless to say, new sub here. Great job!
I once smashed a widescreen changing out the blades because I stopped the wipers the first way you described. Half way through the change I had to turn the ignition on for some reason and when the wipers realigned they hit the hood and came smashing down into windscreen without any blades attached. I’m in favour of reading the manual. Also, cool video. I like how the redundancy is your favourite part; screams Engineer.
I work on my mother's car all the time and every time I need info or don't understand something, first thing I do is go to the manual, there's always a lot of useful info in them, I tell everyone with a car to at least skim through it to learn a bit more about their cars, very useful!
Sometimes it's good thing, sometimes i wonder why they bothered with a paper and not just slapped QR code somewhere on the box. On another hand, maybe they think if someone needs quick start guide the can't figure out how to scan a code.
@@horrorhotel1999 both is good- it wouldn't kill the manufacturer's documentation department to use the same file they generate the print run from to generate an online version.
I'm so happy with the timing of this upload. I borrowed my mother's car since mine needs repairing, and I noticed it had automatic wipers. I wanted to know how they worked. However, I was driving so I didn't look it up on the spot and forgot I cared. I got home and saw this in my notification tab. Thank you, Alec. The itch was scratched, metaphorically speaking.
I don’t usually comment but this video has already been super fun and refreshing to me, then at 7:28 I laughed so hard my dog jumped up and barked at me. Just a perfect example of why I love this channel so much
I absolutely love the manual with my car. It's got full illustrations of every single part, step-by-step instructions on how to do literally everything, full wiring schematics, full descriptions of how every component works, literally everything.
Times have changed. I miss old user manuals. Even consumer electronics had schematics in them. Nowadays I'm surprised if I can get schematics for industrial equipment
My Ford Ranger has Auto wipers, they have been programmed very well and work perfect 99.9%, they even slow down when you stop at a red light instead of continuously wiping, as soon as you take off the brake they wipe instantly, quite smart
The most amazing part of this whole video is that you... you! OF ALL PEOPLE, didn't read the owners manual. I would have bet money that you kept that sucker by your bedside table for a bit of light reading each night. Jokes aside I love your contend. All the best
As a fairly new owner of an Ioniq 5 (December 2023) that hasn't had to change the wipers yet, and is also an idiot for not reading the manual yet, thanks for taking the time to do it for me!
I love your videos and this one in particular hits home with me! I work at Rivian and for a while my line installed the rain detectors and I always wondered how they worked. Thank you!
I have to say. My Mazda has amazing auto wipers. While I mess with the sensitivity in certain misty conditions, I almost never take it to manual. Their blind spot monitoring is also the best I've ever seen. It detects cars racing up from behind you and warns you early before you might even notice them, including motorcycles. It also doesn't warn you about cars YOU'RE passing unless they suddenly match your speed and stay there. What a concept, cough Ford, GM, Toyota, etc.
These sensors were the example my old physics teacher (2015) used for a real world application of total internal reflection. He described a slightly different operating principle which some manufacturers may employ or at least may have at the time. IR light is injected at the edge of the glass such that TIR keeps it contained within the pane, bouncing up and down like an optical fibre. At the opposite edge, a sensor detects this trapped light. Source and sensor both need to be optically bonded to the glass, obviously. Every drop of rain causes a small amount of light to escape by changing the critical angle due to the glass/water vs glass/air interface. It's quite an interesting method which allows sensing of the entire width of the windscreen, rather than just at a single point or small area, but would likely more costly, requiring 2 modules rather than one. I would assume it would be less prone to false negatives due to the larger sensing area, but more prone to false positives, especially it the windscreen ever cracked.
Bless you. I noticed the sensor for the first time in my car a few days ago and had it lingering about what it was in my mind ever since. Bless the algorithm and the universe’s timing
This has to be the cleanest Technology Connections video I've watched in a long time. Some Ford vehicles will allow you to move the wiper assembly to any position on the windshield when it's off, then reset to zero position when the vehicle is started. Can't wait so see how fast old Ioniq5 gets traded in for a new Ioniq5 (now with REAR WIPER!)
I don't have one of these newfangled cars with a device like this, but it's very interesting to see how one works. For my part, I rely on another complicated pair of sensors which, when light passage is obscured to a sufficient degree between the sensors located behind the glass and the road located in front, trigger an electrochemical reaction that forcibly bumps the stock near the steering wheel to activate the wiper system.
Having just purchased a vehicle that is equipped with Rain Sensing Wipers I can appreciate the mention that the system is "effective but not perfect". I constantly find myself arguing with the auto setting when it starts to rain heavily.
I more tend to argue with it when it's not raining much at all. As Alec said, the workaround to "not wiping enough" is to either dial the sensitivity up, or just put it on continuous wiping. If it's wiping too much even at lowest sensitivity, you have to basically turn the wipers off and manually trigger them each time. And salt/sand on the windshield will make this worse every time. I wish there was some way to trigger an old-school "intermittent" mode. Or at least give the wiper control some feedback that "no, that's still too sensitive; even lower sensitivity than that."
@@Nimelennar you might need to dive deep into the settings of your car, my car's sensor doesn't work (as in wouldn't wipe at all beyond the initial wipe when turning them into a higher sensitivity setting) and I could change them to time-interval deep in the settings Of course that won't let you switch between them easily
@@ratchet1freak Thanks, but my car doesn't have a settings menu. The most technologically advanced feature my car has is Bluetooth. I think I might be able to get the rain-sensing sensitivity tuned at the car dealership, but it's not worth the hassle.
@@Nimelennarwhat car model do you have? You sparked the inquisitive part of my brain and now I want to find out if your car has the option to (somewhat easily) change that setting.
I laughed out loud at "not alluding to anything" and now my neighbours think I'm crazy (as I was walking the dog outside at the time I was listening to the video...)
@@tffkap Yeah my X is dreadful. I've learned to tap the windshield-squirt button to get it to trigger. And then sometimes it goes superfast for no good reason....
@@tffkapHad a 2014 Model S that had a rain sensor and the auto wipers worked great (Better that the BMW I had before that). Now I have a 2018 Model S and as long as it is bright outside it works well enough, but once it gets slightly dimmer it has to be controlled manually. Only redemption must be that it still has stalks. As for auto high beams at least here in Europe Model Y and 2021 and newer Model 3s have adaptive headlights that only blacks out sections of the high beams to not dazzle oncoming traffic.
I worked for Acura 20 years ago when they introduced automatic wipers on the MDX. The early models had issues with the sensor interface to the glass. They were prone to false operation because of vibration. We diagnosed them by lightly tapping the glass. The faulty ones would go nuts with the lightest touch to the glass.
My old Alfa Romeo had the sensor pretty much exacly where the length of the wiper blades ended, so even at the lightest drizzle, the wipers gathered a streak of water right at the sensor, making it go faster and faster. It was just one of the dumb ergonomic shortcomings of that car and I loved them all.
I recently bought a 2013 Audi S4. And turns out it has automatic windshield wipers. I had no idea but it is definitely a massive bonus. At the beginning. I was not so sure about it. I wasn't used to it but now I'm just a little patient. Certainly takes a second to ramp up or ramp back down like you said, but I simply have not touched the windshield wiper stock since I got the car
Yesterday i was looking at the rain sensor of my own Ioniq 5 and wondered how it works. And now you delivered the perfect video, even showing the same car 😂 Thank you! 😊 And also thank you for the tip on how to change the wiper blades 😊
My cheap old Citroën also has a position to change them. It is activated with the car off with a single touch on the lever. And it also has a second use. When it snows and you have the car parked outside, it is used to deploy the windshield wipers and prevent them from ending up buried in snow.
I remember years ago on automotive forums people DYI'ed rain sensors with optical mouse sensors. Also, the manual being over 700 pages, ain't nobody got time for that.
When I buy a vehicle, I figure I’m buying a tool multi-function tool worth tens of thousands of dollars. Its two most basic functions are to drive places and to keep its occupants acceptably comfortable and reasonably protected. Other than the very most basic driving controls like the wheel and pedals, every model has differences between every other. Aside from wheels and pedals, most other controls crucial for driving-your lights, signals, wipers, mirror/seat/wheel adjustment, and the Park/Reverse/Go thingy-all of that can vary widely in form and function. Everything else-everything related to comfort, convenience, entertainment, and even basic maintenance-well, nothing is standardized at all. It might as well be anarchy. So I figure, when I spend thousands or tens of thousands on a new or used vehicle, it’s absolutely worth it to go through the owner’s manual so I can be sure I don’t miss any features on this incredibly complex and expensive thing. I like to know what I have and how to use it-all of it. I paid for all the features, so damned if I’m not going to use (or at least try) all the features.
I have been thinking about this topic and hoping you would make a video on it!! Thank you, everything time I'm curious about something I can usually find a video on it from you.
The thing that surprises me the most about this entire episode is that Alec is not the kind of person to read his owner's manual front to back within the first 30 days of buying his car.
I had had my company car for three months, before I RTFM, and discovered it had a 6 disk CD changer hidden in the boot / trunk...
I'm a nerd I give it a solid flip through the first week😅
I read manuals for cars I don’t even own, but am really interested in. It’s a good way to know all the useful little features the cars/devices have.
Side note- I especially hate how so many companies are making the goddamn user manuals web-only, the whole point of a manual is you don’t need a network connection to look something up. I miss pdf manuals.
Edit to add clarity- They don’t even have an option to download a pdf version, it’s just a link for the online manual. It’s much more clumbersome to jump back and forth between sections
@@Highraven I read mine online before buying my car so I knew how to test drive it and what the features were.
@@Highraven - and for my car the delivery was delayed for a week from the agreed date. Reading the manual calmed my nerves.
Alec, stand proudly. You used the manual as intended; as the last resort. You sir, are an engineer.
I just opened my hood when I got to this problem.
If it's not on Google it doesn't exist.
As the last resort? It should be your first resort, especially if you haven't read it. It's often a lot more useful than you might think.
As an engineer I spend the majority of my time reading the manual, or more formally datasheet. So I feel like it's more the first than the last resort.
@@ElusiveDino *That'sTheJoke.jpg*
As a Tesla owner, thank for the first 50 seconds of this video and 8:50. A much needed roasting of Tesla's decision to not include them.
Me too hahhahahahha
Why 8:50? The hood covering the blades gives you quite a bit more efficiency and therefore range, ist smart design. And the button to service the blades is literally right in the service menu in the car, couldn’t be much easier. The decision to not use a rain sensor however is borderline stupid, wipers don’t work well on Teslas now since 7 years and counting
Tesla doesn’t even rain sensing wipers?? Lol
@@GHN1013 They do not have sensors to save money. It's estimated they cost less than $10.
@@PopsGG “To save money”?? And that’s pathetic excuse from Tesla. For a car that’s $60-130k?? More reasons why Tesla should never be considered an “luxury” brand. What other amenities are they missing?
I know you do the low effort videos for yourself, but I would like to remind you, we all watched an hour long video about dishwashers and loved it. I still, to this day, get the hot water flowing to my sink before starting the dishwasher add soap on the door because it doesn't have a place for first stage soap. We love your shit, bro.
Same. I even made my husband watch it so when he starts the dishwasher, he does the same! Now if only I can convince him to pay attention to the rinse aid getting low...
The dishwasher episode was epic. I've learned so much and my dishes are really cleaner now.
Dishwasher video actually changed my life. I’m sure my machine isn’t very high quality but it gets caked on food off all of my dishes so good now that I’m using it properly.
Wait what? What video is that, seems interesting and I can't find it :/
You do realize how much work even a short video like this takes? This isn’t tiktok he doesn’t use a selfie cam and record himself love for 11 minutes then say he’s done for the day. This video even though short probably took weeks of not months to put together if he did it himself. From filing to editing, to audio mixing, graphics that all takes a lot of time if you do it yourself. Not to mention the UA-cam algorithm is probably top of his mind. While it’s not exactly known how it works shorter videos are far more likely to be recommended because they are more likely to be watched to completion which Netflix has said is the ONLY criteria they care about so it would make sense UA-cam follows a similar format since they do similar medium. So I praise him for making such a high quality video especially if all of it was done by himself. And if you want longer videos there a simple solution give him 60,000 every year so he can afford an editor so he has more free time to make longer videos.
I watched a Technology Connections video, in its entirety, in one sitting, and still had time for my life. Who knew that was possible?
Enjoy it. It may never happen again.
You say as you post a comment to strangers on the internet arguing that you have a life. Who exactly are you trying to convince?
You mean to say you don't watch all the one hour'ish videos on one go? Do I have too much time on my hands?
Why did I read it with Technology Connections' voice😂

Some engineer:
- looks at pulse oximeter
- looks at windshield
- *squints eyes*
Technology? Connected.
So here we are at the age old question: What came first, the pulse oxymeter or the automatic wind shield wiper?
@@andreasu.3546 pulse oxymeter. First one was from 72, first automatic wipers were sold 96
"I bet I could fit a bi-metallic strip in that windshield."
@@erebostd first auto wipers were sold in 1970, but also pulse oximeters were merely commercialized in 72-75 - the technique was invented in 1937! it just took a while for technology to get them small / accurate / cheap enough to make it into health care at scale.
"Look, I get it wet, and the car wipes! But two can play at that game-" then using a screen whipe as a transition between frames. Is exactly the kind of joke I love getting blindsighted by between detailed information in a presentable manner, and truely midwestern levels of snark.
I totally didn't catch that, I though he was just making a non sequitir.
I read this comment at exactly the same time as that bit of the video!
*wipe screen
Blindsided, as in from the side you cannot see.
1:01 if anyone is looking for it
I had two very nice surprises recently after buying a very cheap Citroën from 1998. First, it has a rain sensor. And second, It´s by far the best working rain sensor i have ever seen. It never gets confused or start when it´s dry or forget to wipe when it´s wet. It´s 100% perfect all the time. And they did that in 1998!
Too bad Citroën cars are not sold in the United States of America, and I don't know of any 1990s US market cars with rain sensors.
Citroën had always been innovative. Sometimes too much for their own good.
@@Filip_Phreriks They are so brilliant that they had solutions to even non-existing problems. One of my favorites is that the magnificent DS had real-time self adjusting height correction on the headlights....on a car that also has self leveling suspension. I mean, it´s a good idea for headlights to not jump up and down when you go over bumps. But then again, I have yet to see the DS jump at all on any bumps. You can actually take a speed bump way too fast in a DS with a glass of water on the dash without even upsetting the water. Gotta love them...
As a software engineer, thank you for spreading the gospel off RTFM. As a sidenote, the people who need to be told to RTFM also seem to be the people who don't write any manuals for the stuff _they_ make, or don't bother describing 80% of the functionality in it. Not sure what is more frustrating. Telling people to RTFM or finding out there is no FM to R.
definitely the latter
What you try to look up: Change wiper blades
Owner's manual index term: Inclement weather clearing system maintenance
Ha! I think that might be referring to parking outside during freezing rain. You have to put your wipers up, or they're freeze to the bottom of the windshield and take forever to thaw.
That's one thing I love about my Tesla: Wiper Service Mode is just right there in the Service menu. Easy to find. Easy to use. Easy to disable when you're done swapping out the wiper blades.
@@coredumperror but you have to admit, Vision based auto wipers is still crap. I'd take a proper rain sensor over slightly easier blade replacement any day.
@@R.Daneel In my experience, owner's manuals use the most obscure terms for normal things making it hard to lookup anything. Example: Let's lookup turn signal replacement and eventually stumble across "intermittent directional lamp disassembly"
I remember many decades ago spending ages looking for the software code pretty-printer that was listed under "grind out elegant listings"
As a Tesla Model X owner, I appreciate all the little jabs at Tesla.
Well, tesla isn't the only car company trying to make the cabin look more futuristic by moving controls into the infotainment system, or using touch surface buttons... it's also cheaper than actual knobs and buttons...
But it's so annoying to the driver, especially if that driver is old enough to have the muscle memory.
It's all good and convenient with cars that try to help you driving.
But there will be cases where it's nice to be able to override the fancy stuff, and preferably without removing your eyes from traffic.
Leave my gear selector alone, let me manually override lights, blinkers and wipers. And give me a knob for volume and climate control. Let me engage, disengage and adjust cruise control without lifting a hand from the steering wheel.
I also like how Hyundai use paddles to adjust regeneration and how Audi lets you change drive mode while driving, so you can switch to ECO when you enter a town, or you see the battery level disappearing faster than you planned.
Don't make me pull over so I can adjust everything for the further journey in the infotainment system.
And don't try to make me try voice control... as a non-native English speaker I'm sure that I pronounce some words incorrectly, and the Danish voice recognition isn't as well trained as the English one.
When that rant is out, I'll agree that it looks nice and sleek with all that touch and simplified controls... it's just not very practical.
@@BenjaminVestergaardI think he’s more alluding to the lack of auto-wipe sensors in current Tesla models, since they moved to a pure camera implementation that, frankly, is just awful and doesn’t work. All to save a few bucks per car.
@@mobibobobobobobobvobobo well, tesla also made away with the radar and ultrasound sensors... all camera based now...
I can't imagine that working very well for very long during a Danish winter if we have snow, because we spread salt on slippery roads. It creates a nice sticky sleet along the edge of the road, and during snowfall, that stuff builds up and you need to use sprinklers on your windscreen for it to remain clear.
I've experienced that sleet build up to get so bad that the radar didn't even work after an hour on the highway, and the camera based lane assist was not exactly reliable either. That was a Hyundai I think.
Edit: but I'm sure that Teslas all-camera system works pretty well in sunny California.
@@BenjaminVestergaard Tesla headlight alignment also doesnt work properly, also relying on the camera. Automatic MOT fail.

Alex, we've been saying RTFM since at least the 1980's. I've gone through the manual for every car I ever owned and always find something new, unexpected, and useful there. You found your wiper hack. On my 2017 car I found how to get into and start the car even if the battery in the key fob dies.
This video was so quick, I didn't even expect to be showered with new Alec rant time
You have no idea how amazing this video is for me. One day, I wanted to know how this worked on my car, but when I googled “how do rain sensing wipers work” I just kept getting pointed to manufacturer webpages that just say “automatically detects rain and activates wipers” without anything saying HOW it detects rain. It’s bothered me ever since. Thank you!
Hahaha, same here... so frustrating. And asking other people lead to many different, and apparently wrong answers.
How does a rain sensor work?
It senses rain!
Okay.. But how does it sense rain?
It does it automatically!
............
Ah yes. Google is completely useless these days. ChatGPT performs quite a bit better, but is still somewhat vague about the specifics. Nothing beats a well-made video like this where someone did some actual effort, in spite of the Effortstat™.
this is why i love gen AI and AI search engines, I just asked copilot which answered it perfectly. it works so well for those random questions. but always keep in mind it can just make up stuff, so trust but verify
Honestly sucks how much worse Google has gotten as a search engine since even when I was a kid
I once had the privilege of working along side a Technical Author and he worked really hard to create a useable, easy to understand users' manual. He did comment that the manual would only be as good as the information that we (the Engineering Team) provided and the amount of time we were prepared to spend answering his questions. It always struck me as a bit of a shame that he didn't get to put his name on the manual that the customers got to read.
When I was working as a techwriter, there was a spectrum. Some departments (and specific engineers) were awesome to work with, and some would only give you single word answers after being bugged for weeks.
The teams that worked with us had amazing documentation, frequently modified their product as a result of our conversations, and often learned for the first time about related things that other teams were doing.
The teams that didn't engage had minimal (and sometimes incorrect) documentation, and did not get those abstract residual benefits of being in the hive mind of the techwriting department.
EXCEPT that one time when there was something very complicated to be documented, the engineer was far in the "difficult" corner. I wound up having to both run and read his code to get answers to my questions. Surprise: I found some significant bugs by asking questions like "what is this interface" and what happens if you do these two things at the same time"?
Communicating about your work benefits everybody, especially you.
I love this episode.
I especially love pointing out the technology connection between electric ovens and automatic rain sensors.
I love the way you explain stuff
That Effortstat is a thing of beauty! 😂
No! You're wrong! Alec shouldn't be allowed to use that doodad, he should make long videos. This video would have been better if he'd bought 2 cars, just to dismantle 1 to get to the components.
(Isn't sarcasm fun...)

Absolutely garbage auto wipers. My model 3 wipes when it's sunny and doesn't wipe enough when it's pouring
I have a brand new refreshed model 3, and I will happily admit that they are currently absolutely garbage. There are rumors of an upcoming update to improve them, but I am not holding my breath for it. They trigger at the appropriate time for me, but often at the wrong speed (light rain, and they are going crazy, heavy rain, and they are too slow). The one remark I will commend them on, is that they are easily controller via the buttons on the steering wheel in my case.

So, it's never too late to start.
Thank you for explaining how it detects wetness. I couldn't find that answer so clear as you told it. . Also, I now understand why sometimes when I start up the car in light rain, it refuses to wipe. I always leave it on "auto", and now I know it's because of the 'dry calibration'.
Bro "low effort"? This is the perfect amount of effort, I learned everything I wanted to know about the topic and finished the video!

I worked in the automotive glass supply chain in the early 2010s. Sensors like this drove me nuts because the different combinations of them meant that there were nearly *30* different windshield variants for different cars, depending on which package the owner had.

@@craigslist6988just because they don't care doesn't mean that their car doesn't care.
Thank you thank you! I had an intuition very close to the solution but never bothered looking up how they actually work. This has satisfied my itch to know about this for years!
I have had my current car for like 4 years, and I just discovered this setting the other day (I'm bad about manuals), so I was wondering how it works, and lo and behold! It's like my car knew this video was coming, and inspired me so I'd be ready. So far, I've found it's mostly ideal for the kind of light drizzle that's not enough to fully turn the wipers on, but enough that one-off wipes aren't cutting it. That covers a surprising amount of the rain in this area
As a Tesla owner, I fully appreciate the shade being thrown at "any organization in particular".
I do, however, have a wiper service button that is easily findable, so there's that...
but that takes more effort than just pushing a stalk.
@@ashliehigginshe’s referring to the service button which presents the wipers for maintenance
@@ashliehiggins Sure, if you have any idea how to do it. Alec specifically bashed his Ioniq 5 for hiding the method of turning on wiper service mode in the manual. Teslas put that method right there in the Service menu.

Sometimes the smartest people show up in the weirdest of places to solve the most banal of issues. We already have the capacity to turn on our wipers, have for decades. But someone somewhere thought to themselves, "Ya know, I bet I could take $0.50 in parts from our bulk purchases and make a thing that can turn on the wipers automatically..."

Thankyou I had always wondered how the wipers knew when the car was wet. You are truly one of my favourite people
I have a Ford Endura here in Australia, aka your Ford Edge. Went to change the blades and I could just turn the arm and it turned super easy and not connected to a seperate motor with levers, very weird. Turns out each wiper has its own motor with encoders so the onboard module tells each motor when to wipe, how fast and how far. Very clever and complicated. Saves engine bay space as well.

My 2005 Buick LeSabre had automatic wipers and I'm surprised it was on such a relatively old vehicle and not any of the newer ones I've had since. It also had a sensitivity adjustment on the stalk which was interesting. Useful too because sometimes it would get a bit too sensitive and trigger when sudden darkness was encountered, like under an overpass, tunnel, etc. It worked really well overall and I rarely if ever had to use the manual modes

Why is it Alec that even your most "low effort" videos are still effortlessly amongst the best videos on the platform? Kudos!
Thank you so much for covering this, when I tried to look up how one worked, the best answer I could find in the internet was “it works by sensing rain”. Gee thanks.
I have the same car and did read the manual, learned a lot about what it can do, found it worth the time.
Oh my god Alec, you literally helped me save a loooot of time and money by publishing that video!
I have had an issue with my Renault Zoe R135 automatic windshield wiper sensor from since I got it (used). By taking a photo of the sensor I was immediately able to see that the sensor is fine, but that the optical gel is nearly completely gone, probably from a shady windshield replacement in the past.
It seems to be fairly easy to buy a new gel pad and replace it by my own, so thanks both for the (as always) excellent in depth view and explanation of this sensor, and for saving me quite a few bucks!
EDIT: After thinking about the solutions and looking at the photos I took, I realized that it could be that the sensor was not completely clipped in. After disassembling the plastic housing around the rear view mirror, I was greeted with a semi-clipped in sensor. Reattaching the other side re-sealed the gel without any bubble, and the sensor seems to function as normal! I'll just need to see with the next rain.
We have this problem with brand new cars. If you get a tiny speck of dirt on that gel at all, or like a fingerprint or if you drop it on the ground and then try to install it it will not work.
Source: I put this piece on cars all day.
I was also wondering how windshield replacement was going to affect this.
I'm sure it's not just a "shady" replacement company, but any company as getting the right kind of gel and the correct amount, must be tricky.
@@BryTee You're close, they come with the little gel layer already on them and a little plastic cap covering it that you must carefully remove without touching the gel. Ours are manufactured by hella, and we get them I think for $12 a piece.
When we get one that doesn't work they just swap the whole sensor out. But I bet at the dealer these things are over $100.
@@JasonHenderson @BryTee In this case I'm happy to report that the sensor was just not clipped in on one side! I have to assume that the technician who installed the sensor didn't clipped it in fully and that over time it detached.
The gel was apparently undamaged as I tested the sensor and everything seems to work fine! No bubble or anything after checking with a photo.
I was a technical author, and Alex's conversion to RTFM was music to my ears. From time to time a friend calls me because they can't install or fix something. I go round, ask for the manual, consult the manual and install or fix the equipment.
I know a guy who basically made this a second job. He advertised himself as a maintenance guy for any appliance in people's home, had no qualification for it, but he just got the manual for anything people brought to him and used it to "repair" them for a fee. I put repair in quotes because sometimes it was just people doing proper maintenance on their stuff because they didn't know they had to maintain itXD
@I don't think of this as a scam, he's actually earning his keep providing a necessary service. As someone who used to earn my living as a "field engineer" (highfalutin term for repairman with a car). From many years of experience I can assure you that 99 times out of 100 It isn't the device that needs repairing, it's the customer.
Being an IT specialist opened my eyes to reading manuals/documentation. As a kid/teen I loved to dig around and test out different stuff an felt like a genius when I figured it out all by myself, but nowadays I understand that that's actually a stupid approach, where you're just stumbling around in the dark trying random things, only to invent the wheel again after hours of trial and error when you could have simply read some instructions and built your wheel in a few minutes. And that's just in the best case! Quite often you will not achieve anything, or you mess up some settings and don't know how to revert it back, or in the worst case, you end up breaking something that may or not be repairable.
It's really mind boggling how people always think not reading the manual would be the smart thing to do! 🤦
I'm seeing this confirmed right now with my switch from Windows 10 to Linux on my gaming PC that I've made 10 days ago. I've always been using Windows, but got really frustrated with Microsoft's shift away from a user-focused UX towards pushing their own services and third party programs/services on a commission onto the user, regardless of the user's preference settings. Because of that, I've been considering jumping OS for years, but dreaded the experience of having to re-learn using a computer from the ground up on the new OS. I tried Linux a few years ago, tried to get everything running on my own and it was horrible, so I went back to Windows. This time though, I religiously stick to instructions from how-to's and forum posts and it's been nothing but smooth sailing and I can't even imagine going back to Windows anymore!
Granted, there are other factors at play, like choosing a flavor of good old, well supported Ubuntu, rather than a fairly new distro that was Arch-based if I recall correctly and the fact that software and game compatibility (as well as the availability of good online instructions, I reckon) has improved tremendously since then, but sticking to existing guides/solutions, rather than just reading the basics of what I'm trying to do and then attempting to make my own, highly custom solution (with barely any knowledge of the OS) definitely plays a big part in the switch to Linux being a complete success this time!
@@LRM12o8 man [whatever] is a beautiful thing.
I remember once having trouble on a Win10 machine connecting to the internet, and the help button in the settings page literally opened an Edge tab with a Bing search for "Windows 10 help connecting to the internet" (or similar terms). I couldn't help but laugh, it was so bad.
I was impressed years ago when I got onto a unix system (real unix, as linux hadn't come along at that point) and was poking at the manual when a thought occurred to me. I typed "man man" and sure enough, some elder nerd had taken the time to explain how to use the user's manual! Bliss. :-)
I read the manuals of all the things I buy. So... I think everyone should do it too. I always learn a lot of new things about my cars. 😊 loved the video.
Loved everything about your video. You explained the problem well and made it easy to understand even for non technical users. And I loved the vibe, kind of like from 80’s or so. Needless to say, new sub here. Great job!
I love the props from the last video as evidence of low effort. But you just couldn't resist putting some effort into making the effortstat...
I actually know the guy who invented that sensor! 😁 He's exactly the type of nerdy, enthusiastic engineering guy you expect.
Can we please get him a job at Tesla?
@@RichardBrooklyn Why are we mean to him already? Perhaps he's a good guy.
@@DM-rc4yu good one 🤣
@@DM-rc4yu he can give them the rain sensor stuff, then leave, quick in and out. 2 days tops.
@@RichardBrooklynmake sure to promise Elon is securely away on vacation for those days
I once smashed a widescreen changing out the blades because I stopped the wipers the first way you described. Half way through the change I had to turn the ignition on for some reason and when the wipers realigned they hit the hood and came smashing down into windscreen without any blades attached. I’m in favour of reading the manual.
Also, cool video. I like how the redundancy is your favourite part; screams Engineer.
I work on my mother's car all the time and every time I need info or don't understand something, first thing I do is go to the manual, there's always a lot of useful info in them, I tell everyone with a car to at least skim through it to learn a bit more about their cars, very useful!
also I in no forms am a mechanic, I just learn as I go, the manual and youtube have been my biggest teachers
Every time I buy a new car I read the entire owner's manual front to back. It helps a lot!
Be thankful you had a full hardcopy manual. My dad got a summary plus a web address with full manual which is bigger than Wikipedia 😢
Sometimes it's good thing, sometimes i wonder why they bothered with a paper and not just slapped QR code somewhere on the box. On another hand, maybe they think if someone needs quick start guide the can't figure out how to scan a code.
Oh no, now he can ctrl+f for the info he is looking for and find it quickly - I am disgusted !
@@horrorhotel1999 both is good- it wouldn't kill the manufacturer's documentation department to use the same file they generate the print run from to generate an online version.
I'm so happy with the timing of this upload. I borrowed my mother's car since mine needs repairing, and I noticed it had automatic wipers. I wanted to know how they worked. However, I was driving so I didn't look it up on the spot and forgot I cared. I got home and saw this in my notification tab. Thank you, Alec. The itch was scratched, metaphorically speaking.
Exact same situation here, down to the borrowing of my mom's car because mine is broken. I was so curious. When I saw this I got so excited!
I don’t usually comment but this video has already been super fun and refreshing to me, then at 7:28 I laughed so hard my dog jumped up and barked at me. Just a perfect example of why I love this channel so much
I absolutely love the manual with my car. It's got full illustrations of every single part, step-by-step instructions on how to do literally everything, full wiring schematics, full descriptions of how every component works, literally everything.
What car is that? Impossibru with the schematics.
And it's only probably 100 pages long. I have an old car like that. It even has 1980s first aid instructions and how to use the dealer accessories.
Technical writers are cool. They should get more respect. 🙂
Sir, that's not a manual, that's a tutorial for how to build the car from scratch
Times have changed. I miss old user manuals. Even consumer electronics had schematics in them. Nowadays I'm surprised if I can get schematics for industrial equipment
My Ford Ranger has Auto wipers, they have been programmed very well and work perfect 99.9%, they even slow down when you stop at a red light instead of continuously wiping, as soon as you take off the brake they wipe instantly, quite smart
My Ford ranger has absolutely nothing automatic, even the transmission. It's awesome.
It might be tied into the Auto-Start system. My Edge will turn off the A/C as well if its activated, until it starts getting warm again.
My neighbor's Honda Odyssey will automatically turn on the back wiper if the front wipers are on when you put it in reverse.
@@NamesGolden Same. I do got power brakes & power steering though, but no electric mirrors or locks.
@@radbaron No Auto stop / start on my one, I always thought if the wipers were switched on the headlights should just come on automatically for safety
ah yes, the age-old wisdom that none of us seem to remember: RTFM. great video!
The most amazing part of this whole video is that you... you! OF ALL PEOPLE, didn't read the owners manual. I would have bet money that you kept that sucker by your bedside table for a bit of light reading each night.
Jokes aside I love your contend. All the best
As a fairly new owner of an Ioniq 5 (December 2023) that hasn't had to change the wipers yet, and is also an idiot for not reading the manual yet, thanks for taking the time to do it for me!
Hot damn! Quarter of a million views in like 8 hours. Really happy to see this channel be this healthy! It deserves it.
Always wondered how auto wipers worked but never bothered to look it up. Thanks again for satisfying my curiosity!
I love your videos and this one in particular hits home with me! I work at Rivian and for a while my line installed the rain detectors and I always wondered how they worked. Thank you!
I have to say. My Mazda has amazing auto wipers. While I mess with the sensitivity in certain misty conditions, I almost never take it to manual. Their blind spot monitoring is also the best I've ever seen. It detects cars racing up from behind you and warns you early before you might even notice them, including motorcycles. It also doesn't warn you about cars YOU'RE passing unless they suddenly match your speed and stay there. What a concept, cough Ford, GM, Toyota, etc.
wow! TWO technology connections videos in a week? gather the children!
These sensors were the example my old physics teacher (2015) used for a real world application of total internal reflection.
He described a slightly different operating principle which some manufacturers may employ or at least may have at the time.
IR light is injected at the edge of the glass such that TIR keeps it contained within the pane, bouncing up and down like an optical fibre. At the opposite edge, a sensor detects this trapped light. Source and sensor both need to be optically bonded to the glass, obviously.
Every drop of rain causes a small amount of light to escape by changing the critical angle due to the glass/water vs glass/air interface.
It's quite an interesting method which allows sensing of the entire width of the windscreen, rather than just at a single point or small area, but would likely more costly, requiring 2 modules rather than one. I would assume it would be less prone to false negatives due to the larger sensing area, but more prone to false positives, especially it the windscreen ever cracked.
Bless you. I noticed the sensor for the first time in my car a few days ago and had it lingering about what it was in my mind ever since. Bless the algorithm and the universe’s timing
7:23 - "By the magic of having 2 of them" :D
I was wondering how this joke was going to be incorporated
I actually expected the "Two of Them” kitten meme but then I remembered this was Technology Connections, not Cathode Ray Dude! 🤣🤣
This has to be the cleanest Technology Connections video I've watched in a long time.
Some Ford vehicles will allow you to move the wiper assembly to any position on the windshield when it's off, then reset to zero position when the vehicle is started.
Can't wait so see how fast old Ioniq5 gets traded in for a new Ioniq5 (now with REAR WIPER!)
I'm glad I got my IONIQ 5 before they start including that ugly rear wiper! 🤣
Through the magic of buying two of them...
at last! I understand how this works!! thank you ❤❤
I don't have one of these newfangled cars with a device like this, but it's very interesting to see how one works. For my part, I rely on another complicated pair of sensors which, when light passage is obscured to a sufficient degree between the sensors located behind the glass and the road located in front, trigger an electrochemical reaction that forcibly bumps the stock near the steering wheel to activate the wiper system.
Having just purchased a vehicle that is equipped with Rain Sensing Wipers I can appreciate the mention that the system is "effective but not perfect". I constantly find myself arguing with the auto setting when it starts to rain heavily.
I more tend to argue with it when it's not raining much at all. As Alec said, the workaround to "not wiping enough" is to either dial the sensitivity up, or just put it on continuous wiping. If it's wiping too much even at lowest sensitivity, you have to basically turn the wipers off and manually trigger them each time. And salt/sand on the windshield will make this worse every time.
I wish there was some way to trigger an old-school "intermittent" mode. Or at least give the wiper control some feedback that "no, that's still too sensitive; even lower sensitivity than that."
@@Nimelennar you might need to dive deep into the settings of your car, my car's sensor doesn't work (as in wouldn't wipe at all beyond the initial wipe when turning them into a higher sensitivity setting) and I could change them to time-interval deep in the settings
Of course that won't let you switch between them easily
@@NimelennarThey all suck and wipe too little especially when it's bot raining a lot. it should use the camera as a secondary sensor
@@ratchet1freak Thanks, but my car doesn't have a settings menu. The most technologically advanced feature my car has is Bluetooth.
I think I might be able to get the rain-sensing sensitivity tuned at the car dealership, but it's not worth the hassle.
@@Nimelennarwhat car model do you have?
You sparked the inquisitive part of my brain and now I want to find out if your car has the option to (somewhat easily) change that setting.
I appreciate this closelier look
I was surprised he missed that one as well.
Thank you. Your videos are some of the best ones on UA-cam.
Thank you for the great content over the years.
Noticed the wipe transition after the car wiped 🤗
I laughed out loud at "not alluding to anything" and now my neighbours think I'm crazy (as I was walking the dog outside at the time I was listening to the video...)
Don’t worry actually laughing audibly in public is normal, even if it happens by yourself! 😋
I had a model 3, now a model y. The auto wipers and auto high beams suck so much compared to my previousl 2018 chevy equinox lol
Yep my model 3’s auto wipers suck😕
@@tffkap Yeah my X is dreadful. I've learned to tap the windshield-squirt button to get it to trigger. And then sometimes it goes superfast for no good reason....
@@tffkapHad a 2014 Model S that had a rain sensor and the auto wipers worked great (Better that the BMW I had before that). Now I have a 2018 Model S and as long as it is bright outside it works well enough, but once it gets slightly dimmer it has to be controlled manually. Only redemption must be that it still has stalks. As for auto high beams at least here in Europe Model Y and 2021 and newer Model 3s have adaptive headlights that only blacks out sections of the high beams to not dazzle oncoming traffic.
When I bought my first new car I spent a whole day just light-reading the entire owners manual. Something about that was really fun to me.
I just love how a video about a car rain sensor is #45 on Trending. Congratulations, you made it!
It's not even November and you couldn't be bothered to find the TIR angle for your example. I love it! More videos less effort!
It's No-effort Not-november. :)
Effortstat! VHS cassette boxes! It's amazing!
Those are (famously) not VHS 😉
As someone who grew up in a Betamax household, it's so weird to see people use VHS and videocassette used interchangeably.
It was Betamax, not VHS.
You sir have answered a lot of questions i wonder to myself on how things work.
I worked for Acura 20 years ago when they introduced automatic wipers on the MDX. The early models had issues with the sensor interface to the glass. They were prone to false operation because of vibration. We diagnosed them by lightly tapping the glass. The faulty ones would go nuts with the lightest touch to the glass.
Alec ending the video with RTFM! i love it.
My old Alfa Romeo had the sensor pretty much exacly where the length of the wiper blades ended, so even at the lightest drizzle, the wipers gathered a streak of water right at the sensor, making it go faster and faster. It was just one of the dumb ergonomic shortcomings of that car and I loved them all.
I’ve been wanting to know how these things work for years. Thank god you conveniently explained it to me before I had to look it up myself
I recently bought a 2013 Audi S4. And turns out it has automatic windshield wipers. I had no idea but it is definitely a massive bonus. At the beginning. I was not so sure about it. I wasn't used to it but now I'm just a little patient. Certainly takes a second to ramp up or ramp back down like you said, but I simply have not touched the windshield wiper stock since I got the car
I can honestly not tell you how long I’ve been wanting you to make a video on auto wipers.
Yesterday i was looking at the rain sensor of my own Ioniq 5 and wondered how it works. And now you delivered the perfect video, even showing the same car 😂 Thank you! 😊
And also thank you for the tip on how to change the wiper blades 😊
I bought a new Hyundai i20 recently and was wondering this very same thing . Also that trick with the wipers is awesome!
My cheap old Citroën also has a position to change them. It is activated with the car off with a single touch on the lever. And it also has a second use. When it snows and you have the car parked outside, it is used to deploy the windshield wipers and prevent them from ending up buried in snow.
I audibly groaned when I heard "Total Internal Reflection"... Optics was a very 'fun' course that I don't want to relive
I remember years ago on automotive forums people DYI'ed rain sensors with optical mouse sensors.
Also, the manual being over 700 pages, ain't nobody got time for that.
It's more than likely in 3-7 languages, and the index likely takes up a good chunk of it to boot
When I buy a vehicle, I figure I’m buying a tool multi-function tool worth tens of thousands of dollars. Its two most basic functions are to drive places and to keep its occupants acceptably comfortable and reasonably protected. Other than the very most basic driving controls like the wheel and pedals, every model has differences between every other.
Aside from wheels and pedals, most other controls crucial for driving-your lights, signals, wipers, mirror/seat/wheel adjustment, and the Park/Reverse/Go thingy-all of that can vary widely in form and function. Everything else-everything related to comfort, convenience, entertainment, and even basic maintenance-well, nothing is standardized at all. It might as well be anarchy.
So I figure, when I spend thousands or tens of thousands on a new or used vehicle, it’s absolutely worth it to go through the owner’s manual so I can be sure I don’t miss any features on this incredibly complex and expensive thing. I like to know what I have and how to use it-all of it. I paid for all the features, so damned if I’m not going to use (or at least try) all the features.
@@HmmmmmLemmeThinkNo Rav4 Prime or PHEV (in EU) single language manual
Thankfully, most major car companies have the manual available online and easily searchable. But you still need a paper manual for emergencies.
Excellent explanation. Just got my first car with rain sensitive wipers.
I have been thinking about this topic and hoping you would make a video on it!! Thank you, everything time I'm curious about something I can usually find a video on it from you.
