- Self-driving cars are no longer the stuff of science fiction. Google, Tesla, Audi and other companies are taking dozens of prototype vehicles onto the road in California and other states. But before they can take off with consumers, big hurdles need to be overcome.

Can't wait for self-driving cars.
I can, driving is supposed to be visceral and an experience. Having a car drive itself takes away from that experience.
No need for a Driver's License now. Kiss road test goodbye
I disagree with the gentleman from UC Berkley who said it will be decades before we see this. I agree with the Audi engineer who says at the end "I want [Auto-driving cars] NOW".
I believe the "complicated" nature of driving is less "complication" and more "reaction impedance" (if you will). That is, driving can seem complicated, because we are always battling the human reaction time of about 1/3 of a second. The computer "sees" the event just milliseconds after it occurs and has more time to work out a plan of avoidance.
Another example is computers' usage in current fighter jets. A human could never fly a modern fighter jet without a computer, because we simply don't have the reaction time necessary to "stay in the envelope" - it would just spin out of control. What actually happens is the pilot suggests a flight path, a roll, a maneuver, and the computer makes many small, micro adjustments to make that happen. (And of course, there is actual auto pilot for long, boring stretches)
Driving a car is - and will be - no different.
It's not complicated to travel at very low speeds, like 5 miles per hour. You just use the sonar sensors to avoid running into anything that's within a few feet of the car. It's also not complicated to travel above 50 miles per hour on limited access roads (freeways). You just stay in your lane and follow the vehicle ahead of you or maintain your speed at the limit if the road ahead of you is open. In both these cases you don't have to detect and predict the path of a lot of moving things that could quickly become obstacles.
The real complication is traveling between 5 mph and 50 mph on local urban and suburban streets. There the computer vision system has to recognize basically every moving object, identify what class of object it is, plot its path and determine if it's going to become an obstacle, and if it is, take evasive action if possible or stop if not. There are also lots of special situations it has to recognize and take appropriate action for, such as moving to the side of the street for emergency vehicles with flashing lights.
The problem is that the computer's vision recognition system requires millions of images of things to recognize and watch out for. Artificial intelligence has had a breakthrough (using GPUs for parallel processing) that makes autonomous cars possible, but it's still pretty stupid at learning. A person can learn by example after only a few examples. A computer requires a million examples. Artificial intelligence can learn things in days rather than months, but it's still a long process by human standards.
Easy for u to say
Nobody is talking that they can be hacked. I just trust myself.
LOVE IT !! I want it NOW !!
My only concern with self driving cars is how long it would take to charge (I'm gonna assume autonomous cars would be all electric) what with all the equipment that they'd come with.
Very informative but I am against this whole process
i never trust a self drive car.
I wonder if these cars will ever work outside of the U.S. Imagine one of these cars in the future in the chaotic streets of Mexico City or old European cities with extremely narrow streets, lots of pedestrians, bikes, motorbikes, etc. It seems to make sense in the U.S. where most (all?) cities are planned with perfect, square grids, and where streets are perfectly paved and painted.
Perfectly paved and painted... if only! And a lot of US cities aren't perfect, square grids either.
Lots of luck... I have a 1997 Dodge Caravan and my instrument cluster refuses to work. For a while I could bang on the dash, but now (after I broke the needle off my gas gauge) the gauges work only when they want to. If we are building cars that the gauges will not keep working, how are we going to have cars that drive alone?
my car, a mercedes cla of 2016 contacts the garage itself if something needs repairs. You are comparing old cars from the 90s to modern cars. These self driving cars exist already and have milions of miles of experience. Experience that is shared. The cars don't get drunk, aren't distracted and have dozens of sensors were a human only has 2 eyes. Might they get in an accident, yes, but then since everything is recorded, it can be investigated and solutions can be implemented and it won't happen again. They are already far safer than human drivers now.
What world do you live in. Yes you can change cars faster than 5 to 10 years, but someone will be driving those old cars, and the electronics will be a nightmare. Also lets see if you will be driving or sitting in a car you own. Ford is not planing to sell cars to people. They plan to sell them to Ubers and Ride Share companies. The plan is to prevent personal ownership. Why do they state parking places will not be available. They want to take personal freedom to travel cross country away from people. Get it.
I think that's the future actually, no more owning cars but using things like uber to bring you from a to b. When it dropped you off it can go park itself or drive to the next person who needs a ride. Most of the time peoples cars are just on the driveway or parked anyway.
The cars are capable of driving in todays traffic. Check how googles car operates, it's fascinating.
Doesn't mean you are not going to be allowed to travel cross country. There are other means of traffic. For instance, car drives you to railway station, take a high speed magnet train to the other side of the country, ask another ride self driving car to drive you to your hotel or other destination. If any, it's going to bring more travel freedom.
well if you're in the US, the government already tracks your every move if you travel by car, be it by your cell phone or road side camera's, or even satellites. you're probably more discreet travelling by bus
and yes even old cars will soon be driven by robots. it'll be a sort of squid like skelleton, using a smartphone for computing power and sensors. today it's a complicated system that costs $1000 and only works on select (modern) vehicles, but by 2022 it'll cost $50 and work on any vehicle a human can control (including planes, boats, bikes...)
at which point governments will simply ban human driving. it'll be more risky than using a busy mall as your shooting range, and we don't allow that either, for good reason
and the fact that few people will own their own vehicle anymore will be the best thing ever, it's way more efficient to have self driving Ubers
Sander Van Ransbeeck _"at which point governments will simply ban human driving. it'll be more risky than using a busy mall as your shooting range, and we don't allow that either, for good reason"_
Sounds great! After all, freedom and independence is _so_ overrated. I'm also against banning tobacco as well, even though it kills _way_ more people than automobile accidents alone.
I agree with the guy from Berkeley. I fell like this a billion dollar distraction from the real automation in farming, manufacturing, warehousing, and retail.
1. Warehouse:
Amazon needs 20,000 fewer workers then last year. Thanks to automation they think UPS, USPS, and FedEx will follow suit next year and we could we see almost 100 thousand jobs cut from warehousing and distribution next year.
2. manufacturing:
Dark factories getting thier name from the fact that are so automated they don't even need to leave the lights on. China is automating faster than the USA seeing reduction in labor to run a factory by 90% America and Europe will likely follow suit to stay competitive. Even steel manufacturers only need need 14 employees to make over 500,000 tons of steel a year.
3. Farming:
Robots that pick strawberries, apples, plant, weed, spray, and harvest lettuce. Milk machines so cows can milk themselves. Vertical farming has finally become profitable. They think that by 2020 farm worker will make up 1% or less by 2020.
4. Retail:
Amazon's GO store, self self check out for retail and fast food, robots that clean the floor's, pizza making machines, burger flippers.
Time scale for these technologies:
This technology is here now not some theoretical future. We do a lot of jobs that are not going to be around in ten years. Just like the telephone/elevator operator's, projectionist, and typeset these are the real jobs on the chopping block for the next ten years not taxi, truck, and Uber drivers.
Outcome:
It's the customer base of the driving industry that will disappear long before they do.
nobody actually wants a self driving car. there's almost no consumer demand for them
Hayes Riviere because everyone thinks they can use their cellphones and drive.
Mike Miller they can but at the same time should look at the road
when. are. they. combing. out
Soon.
Still won't work
So how will people survive when their car automatically drives the speed limit and stops for red lights and stop signs. Makes the concept a non starter.
I'm sure there will be hacks for them, to enable them to drive more recklessly.
Anony Mous lmao...you nailed it
What if you dont need a speed limit at all because the car can automatically calcuate the speed needed for a determined road
i found this idea pointless ! if we allow or to let the vehicle to control drive or self drive still we face the same problems
which is traffic ! So i do value this advance Technic with all there new sensor system and more electronic . but as a London driver i am looking forward for uk government to sign the legislation and allow the engineer to design a vehicles to fly
on the sky which i believe its more safer.
who would buy a car that can only drive its self only in certain situations ? don't waist your time doing half the job. we want fully automated vehicles.
My Tesla can already do this
thry are . going . to . help . a . generation . of . senior citizens by . giving . them . independence also kids moving them from . home . to school and Back afternoon classes
if you want it right now, buy a Tesla then :P
They're so expensive though.
Meh..I'll stick with my 54 Olds...
+Joe Arredondo commute with an autonomous vehicle and take your 54 out on the weekend
