Yes, an ideal AV would not crash into another vehicle (well, the black ice may be a rather severe test), or crash only gently; however, how could it avoid being hit by a vehicle being driven by a human, at high speed?

The AV will see the stopped car much farther out, and will begin breaking much sooner, and thus will likely not be breaking at its maximum rate. This means the human driver coming from behind will have a longer time to see the break lights and react by also breaking. This won't eliminate 100% of such crashes, but it will eliminate a large percentage, while reducing the severity of the remainder.

And then I open Horatius' All Robot Repair Shop, which doesn't play such games, and I dominate the market, because it no longer matters if I'm farther away from your house, since the Robocar will be the one wasting time getting to my shop.

How much trouble is a taxi-driver in if they ignore obvious signs of distress?

Can an AV be sued for an almost certainly avoidable death due to a heart attack ("If only the AV had diverted to the ER, less than a minute away, instead of continuing on for another six hours to its set destination", sort of thing).
I expect that we'll some day have an emergency panic button in cars, that tells them to drive to the closest hospital/police station, or whatever. The car immediately becomes effectively an ambulance, with similar priority over other cars (probably communicated via some kind of ad-hoc intercar network). Once the button is pressed, it can only be overridden by an official like a police officer or ER doctor/attendant, and misuse has severe penalties.

I like that idea. It might be as simple as "get me out of here now!" command. A car should have some sort of input (such as a keyboard) so that if you leave home and then decide you need to go somewhere else you are not stuck in that car, even if it is not an emergency.

Summary. Poorly marked lane markings confused the computers. The lane markings were worn out. This is something computers will have to be taught how to live with.

I had a similar near collision a few weeks ago. The highway near me had changed the lane layout, but the old markings were more visible in the late afternoon due to how the sun was shining off the remnants. A truck following the old lane markings nearly hit me while I was following the new ones. I locked up my brakes at 70 mph and she flipped me off completely unaware of the mistake she had made.

I agree that this is something computers drivers will have to be taught how to live with.

Which highlights the limitations of vision only systems and not utilizing mapped data with lidar and radar.

More likely connect to 999 services and they'll determine the appropriate response.

I'm afraid your premise is wrong. We will never have self-driving cars in generic, fully autonomous use. By the time that technology is feasible, maybe in 50 - 100 years time, people will have come to their senses and realised autonomous air travel is the way forwards.

But won't future robot cars be able to fly? Surely that'll be easier to control than trundling along on wheels.

Great! We've identified a problem, and can now work to correct it, which will improve the product in the future. This is what testing is for. This is the system working.
