Google has had this for years.  The problem isn't the technology, its the liability.

Liability ultimately comes down to the driver. Case in point:

I will be the first guy to buy a self driving car

But how will cops make any money if they can't ticket for every bullshiat traffic violation under the sun?

'Drunk driving' roadblocks where they search every car because fark you that's why.

Thank god that's unconstitutional in the US now.

"It is thought the car will be able to drive on its own in most situations but will still hand control back to the driver during difficult situations such as dealing with traffic lights."

I'm glad I'll still have a decision during such life threatening choices as "stop or go."

If you put ethanol in your tank, they can arrest your car for a DUI.

Meh, I've been doing this for years.  It's called Metro.

How does a hands free car work when the roads are covered in snow or if there's heavy rain?

Same as hands-on, only with the benefit of accelerometers, gyroscopes, and other sensors.

Not exactly. You could say that the *techniques* are there, and the techniques constitute a significant portion of the technological effort, but the technology isn't strictly there.

I talked to a guy in the biz who works with these systems, and he said one of the outstanding issues they're still dealing with is how to manage & fit the significant amount of computation needed for these systems onto a standard consumer vehicle. Right now the entire trunk is essentially server racks & power generation.

This guy only worked for one of a number of places trying to bring this to market, however.

As far as liability goes, I assume that going forward there will be a certification process similar to what the FAA does with airplanes: verify the hardware and software, ensure correctness under assumptions, and pray to God that you thought of everything.

I should also point out, the car industry types have lots of experience with building computational systems that consist of swarms of embedded microcontrollers distributed over a network. I really have no clue how they're building these systems, but the amount of computation is orders of magnitude greater than existing cars.

It's not a simple matter of throwing in a powerful computer... as I said above, these systems have to be verified to be correct under all possible circumstances. Not so easy.

Self driving cars use cameras to "see" the roads. If everything is covered with snow, they can't see where the road ends.

Any complete self-driving car system would have some kind of depth-sensor beyond plain visuals (like LIDAR on the Google car).  Who knows what the success rate is, but that is at least being addressed.

In theory you could try to use only twin cameras to sense object surface depth (like humans do) but LIDAR is probably way more reliable.

After a search, I found countless stories saying that Google's cars have problems with snow covered roads. Also, there isn't a video to be found of them driving in snow.

Well, then they haven't figured it out yet.

That said, humans also have trouble driving when there's so much snow that you can't see the lines, so I'd like to know what is meant by "have problems." There's hardly a gold standard of human snow-driving to aspire to anyway, aside from a handful of professional ice road truckers and hardened veterans of Minnesota winters. Programming the car to "go slow and avoid collisions" is pretty much as good as a typical human would do anyway.

A human can see where the road would be while the Google cars rely on things like the lines on the road and curbs to determine where it is.

Why wouldn't the car be able to "see where the road" is too, using the same other identifiers that humans do?  I don't know how far they've gotten in terms of actually programming the thing, but based on the hardware they already have, it's perfectly possible to a) train the car to "see" the environment, and thus pick out the road, just like a human would without the benefit of the lines, and on top of that, b) use LIDAR to constantly maintain a 3-D model of the reduced "gulch" of the snow-laden road, as well as the movement of other cars on it, and come up with the best notion of a "lane."  This lane may not be the same as when the road is clean--for example, 3 lanes my become 2 because the roadway is narrowed, and thus the best path is directly over a hidden painted line.

Again, who knows if they've actually developed the product that far yet, but there's no reason why they can't.
