If applied correctly this could solved a lot of traffic problem. I still don't understand why cars don't have a retractable bar under them. So you normally drive everywhere, but big roads like highways are in fact rails where your car gets on.

That idea sounds too simple to be true, but I'd file that under "crazy enough to work"

Not exactly real-world conditions, but a nice demo nonetheless. Maybe this is how they've been able to Street View so much of the world?

I wonder how long until we see the iDrive. I'd love to not-drive myself everywhere, it's a massive time-sink IMO, I could be doing better things in the same time period. I understand some people enjoy it, but I don't.

Unless all cars are driven by machine, the driverless car won't make a huge difference in our lives. You can already experience the magic of not having to drive by paying someone else to do it for you. The real gains of automation occur when a machine doing the job can do it faster than a human. Computers calculate and communicate faster than people, and factories/robots build stuff faster. A machine driving a car ha…

This is wrong of course. Imagine you could hire a driver, now imagine he worked for free and was always at his best driving ability.

The things that self driving cars will do first, really really well, are: 1) Drive people around who currently use chauffers because they can use the driving time productively. 2) Lower the barrier to attending events, restaurants, etc in urban areas where parking is an issue. (if you car can go park itself a couple of miles away and you can phone it up when you want to go home, win) 3) Reduce the number of DUI accidents as people go out, have a good time, and their car drives them home.

Self driving cars that can drive amongst human driven cars will be a huge win. Now why a search company would do with that, who knows.

AFAIK, these cars are still being manned by the engineers, they're not used in any official capacity.

I have seen one on the 101. They are very weird looking things when you look in and see that the "driver" is on a laptop. It's pretty freaky.

Driverless cars are not going anywhere until they can prove themselves 20% superior than the average driver in ALL the following conditions: Dealing with Rain (visibility and deep water on the road), Hard to see tire eating potholes causing damage, Ice and snow (on road and caking on instruments), Snow accumulation ruts, causing car to move unexpectedly, Evasive driving - cutting across a lawn, (avoiding the pool and…

Interestingly enough, a car which simply refuses to drive in hurricanes, hailstorms, white-out snow, and so forth would be rather more than 20% superior to the average driver. So that's easily dealt with - if insufficient sensory data is available, either hand control over to the driver or, if possible, pull to the side of the road. The average driver likely does really horrible in large crashes and pileups, so merely the lowered reaction time might allow a huge improvement there (humans take a really long time to react, compared to computers). The average driver doesn't need to do evasive driving (as well as likely being horrible at it), so that's an unnecessary criteria. Similarly with tire eating potholes; even a tiny improvement would meet the 20% requirement you propose.

Ambiguous/contradictory road signs and unmarked roads are a navigation problem; given a sufficiently accurate database, as is likely to be present in most cities, they would be irrelevant (I expect that initial roll-out of driverless cars would occur in cities, where most traffic would be low-speed and highly structured. I may be wrong).

Unexpected car movements (due to snow, mud, or whatever else) I would agree to be fair things that need to be targeted, but I very much disagree with strong AI being needed for all of this. However, it's probably going to be quite a long while until the equipment is less expensive than hiring someone else to drive (which is a barrier for some group behaviors and sharing of data between cars). On the other hand, that's not necessarily a consideration which people factor in when buying extremely expensive cars.

I think your 20% figure might be low, but that doesn't mean that we won't see specific applications for autonomous cars earlier. Autonomy is going to creep into autos slowly, things like: anti-lock brakes, adaptive cruise control and collision avoidance are all small pieces of an "autonomous" automobile.

A car dealer at the Ford dealership told me Ford is demoing cars that parallel park themselves.

For most of those conditions, safely pulling off the road and telling the human to take over would be satisfactory.

Possibly because the necessary switching apparatus would be a nightmare with modern technology, and would have been entirely unworkable even 20 years ago. That said, it's a really good idea, and one which I would like to see attempted - or at least a good explanation of why it would be completely crazy on a technological level.
