Some newbie drivers right now will never experience the pressure when driving a manual and an uphill traffic occurs. Especially when you're a beginner and you can feel your car rolling down and you can hear the honking of the car at the back😂
i didnt have HSA, and i have 3 pedals. I just move my feet fast enough that i never even have to use the handbrake. dont know what kind of a driver would need HSA in a car with only two pedals when the driver have both legs ?
@@RidewithRevin new cars, new drivers wont understand moving our legs fast enough that even gravity cant pull us back.
@@lalmuanawmahlawncheu6997 true thing
My legs be like jelly during such situation
@@RidewithRevin stop being cocky mate it's specifically designed for auto transmission so it doesn't break the transmission unlike manuals which don't need hsa.
The HSA I learned to use is the clutch and parking brake.
parking brake is the easy way, if you have enough skill you dont need it.
@@xxn0cturn3xx On steep hills it´s better to use the parking break, otherwise you wear the clutch unnecessary.
@@qq84 No, you just need to be quick.
@@kenmore01 you wouldn't have time to ride the clutch
Please explain me how, it will be very much helpful
I usually let the car behind me hold my car in place.

Riding the clutch anyone?
@@ethanebang7507 yup, thats the way I do it as well. Never use the handbrake unless I have to wait for a longer time, just to be easy on the clutch

@TheGaming Hobo lol... I feel he might be taking about clutch pedal if the transmission is manual.
Auto transmission
@Tournel Henry It's maybe better but it makes you lazy and it's boring just turning the wheel around.
how do u struggle with hill starts in an automatic 💀
Now that person can never master clutch 😂
Bad drivers will find a way.

Literally, just use your other foot to go on accel jeez
I know.. I mean in a manual it can be a bit awkward for a new driver but how anybody struggles in a car with only 2 pedals is beyond me
Interesting how it is assumed that only automatic transmissions are used in cars. Outside the USA, that is often not the case.

It's an Indian Channel....😅. And we mainly use manual transmission.
@AutoFuturo "... Stop Your Lies 😂" .The channel founder is Sabin Mathew , an IIT Delhi Alumni from India. And as a nail in the coffin the founder is from my home state. Still don't believe : en.everybodywiki.com/Learn_Engineering#History_and_Start_of_the_Channel
@AutoFuturo Seriously what made you think that Indians are not capable of running a channel like this 🤔.
@AutoFuturo That's Engineering Explained....I make that mistake sometimes too..No offence taken...😊
Wow they dont explain this that well when you buy a new car. They just tell you that the car has abs, hsa, hid, cbd, tbh, icu, pcu, tcc, abc, fox, sky, cnn and etc.
You forgot thc

Hahahahahahahhahaha
You missed xyz and bla bla
You missed sex it is really important
This is really interesting! I've only driven manual cars, so assumed that automatics were holding the clutch partially engaged for you, rather than holding the brake on.
There's no "clutch" in automatic transmissions. However, the drive shaft and the engine are still coupled so the car will be held stable if the hill is not steep.
@@MrAmgadHasan Really? How does it achieve variation of gearing ratios without the ability to disengage?
@@matthewwilkes6162 It uses a Torque converter. Think of it as a hydraulic pump that then can be adjusted in terms of flow and ratio. The only problem is that it wastes energy, but modern transmissions have a clutch that locks the input shaft to the output so it's not there once you get to speed. And in Electric cars the electronics can also just keep a force applied.
@@LaserFur Well you are right but Audi for example uses a double clutch transmission.
So while BMW uses a torque converter Audi uses an automatic transmission with 2 clutches. So saying that automatic cars dont have a clutch is not always correct. But it is correct that they dont need a pedal for it.
automatic vehicles don't have a clutch, a converter is used in place of that
clutch and break are more then enough to beat the gravity. And knowing to control it is true driving skill
It's not about skill. It's about usage of technology in convenient driving. Generally people who can spend extra bucks for automatic talk these things.
@@sivasagarjagga6445 absolutely. People buy manual as it's cheaper and talk about skill and all.. funny people.. they like to struggle and call it enjoyment. No one can save them😂😂
Technology is to make our life easier to drive.
@@sarathc6794 In search for comfort, we lost skills
@@rahull9155 Dude, you are missing the point. For example, if am a camera man of this generation, I dont want to use a 70s camera for my work. The new digital cameras are way comfortable and easy. Obviously the 70s camera will need more skill to operate. But that not the point, its about the technology advancing for making any task more easier and comfortable.
It's funny how this video was recommended to me today. Because i was helping a woman for few hours ago who couldn't start her car on a ramp. So i got out and help her i did it for her and she was grateful. And i was happy to help her and all the cars behind us was really calm. 👌
This would have been nice to have on my stick shift truck when some idiot would stop at a red light 2 feet behind me on a steep hill.
What, you never used the handbrake and floored it in first gear?
@@NoorquackerInd Having a floor parking brake makes that pretty difficult lol
@@devdb2 Exactly. 👍
It's such a dumb system in manual transmission, I have it in my work truck, it holds on hill up or down, but as soon as you press the clutch it comes off, and you roll back anyway cos it has an electric clutch, it doesnt have a bite point its just on or off, you either stall, or roll back into the car 3mm behind you!
@@timfagan816 electric clutches should be progressive not on/off. I would say yours has a fault.
I would still prefer the handbrake technique. Its effective and fun.
What a noob.
Have fun while having a traffic jam uphill. Can't believe how effortless it would be with autos.
Hand brakes are there to assist you in this sweaty situation. Nowadays even some manual transmission cars come with this handy features, and especially handy here in hill towns.
You are amazing. Congrats for 4 M subs

As an old-school manual transmission driver, the hand brake is our hill start assist 😁
Here in La Paz, Bolivia we're used to starting uphill with manual transmission and without handbrake, it's so easy. (even with heavy vehicles) 😎
With manual transmission, driver has clutch, which doesn’t exist on automatic transmission cars.
I think an alternative to this HSA is, the driver use two foot to control the pedals in hill start situations: hold the brake with one foot while applying the accelerator with the other, once the accelerator pedal is applied enough, release the brake pedal and resume normal operation
@@yzhang8629 I saw a Wolkswagen Tiguan with manual transmission and HSA from one of my professors.
The alternative is to use one foot in both the brake and the acceletator, and the other one in the clutch, that one foot operación we call "hacer puente" literally "Do a bridge"
and believe me we have up to 35% slope here in LP 😉

@@juancarlosarzecalle9089 Yes, manual car can also have HSA, it is a great tool to reduce the workload of a driver. It is a trend to make driving much easier, from power steering, cruise control and ABS, to more recent front collision mitigation, lane keep assist and adaptive cruise control
@@juancarlosarzecalle9089 Most Westerners refer that technique as "heel-and-toe". Used in motorsports when braking, rev matching, and downshifting at the same time.
This is a boon in uphill tight traffic situations when the vehicle is held in place and from hitting the vehicle behind..👍👍👍
Very insightful. Thank you
This video was made before they invented the clutch.
Have you ever herd about automatic transmission ?
@@dkgeyi4582 have you ever heard about a joke?
@@dkgeyi4582 Can you ever think this video is stupid and this dude made a joke? Have a common sense, please
Jesus ffing Christ some people like you tho smh
In Malaysia, drivers must pass the stop and go on hill test in order to get driving license. The car use during the test has no complex driving assistant electronic system.
Same in Brazil
Its a driving school of course 🤣., Its like when you are a kid your are learning how to write by your hands but when you get older you often uses devices like cellphone and computers.
The honk from the back is my motivation
Impressive idea and video
I have been driving only a few months now (I'm a European and the car is manual). So if the hill isn't that steep I just quickly move my right leg from brake to gas and then slowly release the clutch. If the hill is steep or I know I will wait longer (traffic light for example) I use the handbrake and do exactly the same thing just without having to use regular brake at all. It's really not that complicated. Also my car doesn't have HSA
I passed my mannual driving exam 6 yrs ago.. a bit panic in hill area during my driving lesson .. but i passed!! Now i'm using automatic car without going to driving lesson.. great video 👍👍
manual is better and more fun imo
@@theobvu no it's not. It's more stressful
@@megachristina12ifyvery stressful . The reason why I stopped manual was because of the hills starts 😩😩. I always got so anxious , fear starts taking over . Automatic is just so much more simple and less likely to cause an accident .
Awesome video explanation. Thanks
Really interesting...thanks for sharing
Very useful for high traffic areas. But for long distances, I find manual driving more enjoyable.
I'm a more attentive driver when driving a stick. It's particularly helpful in slippery conditions, etc.
I use the clutch and accelerator method. Well I like that way
Great job!
There has been a technology that has been there for ages. it's called a hand brake.
“Hand brake” is not operated by hand/handle anymore on a lot of new cars, it is controlled by a button or a foot pedal with ratchet mechanism
Well, seeing it's a woman-driver, a simpler solution don't let women drive

LOL
(just kidding SJW)
@@ronvoy Yes. I miss-spelled and auto correction messed it up
@@cooldesertknight9013 you can either simplify the person or the vehicle.
@Mikolaj Kraszewski Nah it's something that my yung generation doesn't know...It's called driving skill. Why is it too much to ask today, to operate more than 2 imputs at once? When you do it often engough, your body will do it automatically. It's just muscle memory and saves a lot of mechanical and electronic complexity. But that's fine because everything is meant to break within a decade to keep the economy going.
A rachet mechanism is also a solution but brake system would have worked better hence is adopted. Great 👍
With that mechanisim u would also need to find a way to deploy it and disingage it as well.
Bhai mera 1 youtube pr chanel hein. Bhai log mujhe suport ki bhht jrurt hai pls suport kro❤️ua-cam.com/video/JyBckyDgKc8/v-deo.html
A ratchet system would increase mechanical complexity and additional parts that experience wear and need service. You would also need components that disengage the ratchet, adding further complexity. You don't want ratchets in systems that move at speed for extended durations without some form of retention mechanism (which would likely be hydraulic or pneumatic actuators). The HSA is an electronic ratchet, so to speak.
So, yes, the HSA is a vastly better system than a mechanical one.
Amazing video, I learn much in this channel
That’s why a manual hand brake is useful.
True, I have this system in my car but I find myself using the handbrake plenty of times... :)
I use another technique. I have pressed both clutch and brake pedal while in 1st gear, so when i need to go off i just release clutch to the point where car starts dropping RPMs and start shaking while holding the brake, when the car starts doing these things i just let off the brake, give it a little gas and let off the clutch if needed.
That’s how I do it as well. As soon as you feel the clutch is holding the car you let of the break and your good. I’m in Prague right now and they have some hills here and there. It’s funny to see how everyone is rolling backwards when the traffic light hits green 😂
Sorry to tell you this, but when the car starts shaking, you're slowly burning up your clutch.
Great detailed explanation
Such a wonderful info
2:27 "This is a tedious task" * shows lady just press a button *
I prefer having full control and just prolong break with a button.
Exactly. Most accidents where people mess up the pedals is due to automatic cars. With manual you press the clutch and the power is gone. Much more control over a car when it's manual.
@@soldiers303 You can cut the power by shifting to neutral, regardless of transmission type.
@@soldiers303 True. If you learn clutch, you learned the entire car. It does everything. Move your car, stop the car, shift gears ect.
I hired a car in the UK a few years ago and never noticed that there was no handbrake. When I came to a hill with a lot of traffic moving slowly and stopping from time to time, I looked frantically for the non-existent handbrake and was holding the car on the clutch. Then I discovered the HSA.....
Or maybe there was an electronic handbrake...
Yeah,.most probably the handbrake was electeonic
This is awesome 👍🏻
Excellent explanation. 🇬🇧
I already have this on my truck but I never knew it was called a "Hill Start Assist". I have always just called it my left foot..........
You are supposed to use the hand break.
@@jasonburguess We are talking about steep hills and not overloading our clutch.
@@jasonburguess I ruined a clutch once without using the handbrake (very steep hill). Best to use the emergency brake to avoid damage to the car.
I guess this technology or innovational feature they put into a car greatly helps for beginners I guess but the simplest technique available for me is to engage in neutral while the foot brake is all the way in then lifting the ebrake while hanging then when about to move shift to drive and release ebrake then slowly on the foot brake. (For automatics)
Understood! Thanks
Wonderful information thank
Electronic gadgets are great and all, but in this case I'd still prefer the big dirty old manual hand brake..
Yep thats prety usefull if you know your car :D
Bhai mera 1 youtube pr chanel hein. Bhai log mujhe suport ki bhht jrurt hai pls suport kro❤️ua-cam.com/video/JyBckyDgKc8/v-deo.html
Or if its a n automatic which it probably is, *just dont be lazy and use both of your feet* press accelerator whilre holding the brake (also gives some nice engine revs) and then release the brake to start moving
Great video on something new
Great Explanation
When I did my licence test in the 80's I had to hold the car on the hill with the clutch. No hand breke was used. Now days the hand brake is compulsary on hills. I only wonder what will happen when that handbreak cable decides to snap while stationary on a hill.we had to learn complete clutch control. I even taught both my sons how to use the clutch on hills just in case the hand brake stops working.
Using clutch to hold the vehicle is very dumb. Causes high clutch wear & overheating. No manufacturer recommends it.
Because holding the car in place with only the clutch damages the car.
James, I hope they're quick, or they're burning up the clutch. I do respect your intent.
The way I've learned to drive a stick shift car, it's pure adrenalin than this toys.

Very nice explanation
The moment he says ' Sorry Gravity ' was really funny XDDDD
When I was learning, I had to accelerate, release the clutch slightly, feel the car's momentum & then accelerate more & release the clutch fully & let the car move.
People dont seem to learn that anymore which is really sad.
I did this in public road for practice
The other driver weren't happy
Wow is so innovating, they need so many years to understand what we need for drive
Good job. I love electrical project.
It doesn't take seconds to switch between the pedals, just release the brake and quickly press the accelerator more than usual. The car doesn't immediately start rolling back at full speed
Between vaping and recording my next titok video it can take anywhere from 10 sec to 2 mins to get foot back on the gas pedal...
Worthless except for about 4 steep hills in America with stops in the middle.
Not it does. That happened to.me and I was traumatized
@@timcook4552 then you don't know how to drive
@@YourDadsBoyfriend I just started to learn how to drive and when I pressed the gas it accelerated too fast I almost collided
Yeah it goes rolling back slowly but sometimes when I press the accelerator too hard my car starts making a squeaking noise so I lightly press it till it starts going forward
Imagine requiring all those electronic systems and assists when you can just use the handbrake.
Yeah exactly
Starting at a steep point?
@@paulinhoxavierii3744 yes

- how does hill start assist works?
- it olds the breaks for a sec when incline

I partially release the clutch enough to avoid the car go backwards, then throttle, then fully release clutch. I don't use handbrake.
dependingt on how steep the hill is, this maybe wont work because theres not eneough power at idle or you stall.
@@Coolgamer400 There actually is. Just give it enough gas and you get over every hill without hand brake. You just need to be fast.

This is why the hand brake was invented! No need for HSA in my opinion and on manual transmissions then you have hold it easily on the clutch.
On a steep hill? Never,only if you apply the hand brake Wich not every driver want to do it when they stop
@@tamasbogdan9493 the handbrake is much smoother. When I had to use hill assist it jerked me forward every damn time and it stops you from being able to roll forward :/
@@tamasbogdan9493 a properly functioning hand brake will hold the car regardless of how steep the hill is (tyre grip permitting of course). Any driver that relies on technology over the manual controls is not in proper control in my opinion. Hill starts are a fundamental part of operating a vehicle in the real world.
The parking brake technique works best. It works with any type of parking brake, but may require a bit of practice.
But cars these days have cancerous PRND knobs
yea if you drive an automatic@@likhith-lexus
Great information 👍
Nice Animation I understand ...Thank you
As a manual transmission driver, I hate hill start assist. Sometimes the HSA doesn't release for a few seconds and it makes it feel like the car is being dragged. I miss my 2003 Honda Civic that would slide backwards when I took my foot off the brakes.
Wtf
As a manual transmission driver, I found this comment disturbing.
Bruh im 17 and drive a stick
@@offgridgaming9886 gay
You just pull the emergency brake when you stop uphill and then buit up rev then release the hand brake and baam no going backwards
Wooden match stick standing up against tread of the rear of your tire. If you snap the match upon hill start, back to driver school for you!!
"few seconds to switch from brake to accelerator pedal" LOL reminds me of some scene from "Fear and loathing in Las Vegas" movie when they've been really high on some drugs 😁😁
I disabled it almost immediately on my 2020 Ford Tourneo Courier, after 32 years of driving I am so used to the car rolling on a slope it felt weird and annoying when it didn't. It often makes manoeuvring so much easier if you can roll backwards rather than having to bother to engage reverse gear and drive backwards. I use the (mechanical) handbrake copiously and uniuntentionally rolling back on a hill when moving forwards just isn't a problem. Maybe it is more useful if the vehicle has an electronic handbrake, I hired a 2020 Citroen Berlingo and the electronic handbrake would only release with the brake pedal pressed, which counters the normal hill start procedure!
Try using a manual on a steep hill. The car will roll back, but you have to be quick to let off the brake and clutch and hit the gas about the same time or you will roll into the driver behind you or stall. Takes some practice but it's quite fun to do. I always try to see how fast I can move forward with minimal roll back.
Have you not heard of the HANDBRAKE, or what it's used for?!
Tell me you’re inexperienced without actually telling me you are.
Also explain about how decent control system works, please?
Possible a cruise control for low speed only
This is hilarious. This tells me so many people do not know how to drive.
Superb....👌
I used to do all this with my left foot on the brake or in a car with a clutch with the hand brake. A foot operated parking brake was a bit more problematic.
When driving an automatic one should NEVER use both feet.
It has to be a VERY steep hill to cause an auto to roll back.
Why would you want an auto anyhow?
Much better control with a manual.

„a few seconds are required to switch from brake pedal to accelerator pedal”
Does it work both ways? If so, than don’t drive any car
its takes only split seconds to switch from brake to acceletor pedal.
try using hand break and clutch...
@@saberirs178 it isn’t necessary if you can drive a car
You can't just smahs the gas pedal in when starting with first gear otherwise you'll lunch yourself forward and smash into the guy ahead of you unlike the break that you can either ease in to stop or can smash it instantly in an emergency.
So yeah, switching from break to gas is slower than switching gas to break.
