How about an animal jumping in front of your car - a very common situation - when there's no way to avoid it. Computer could assume it's a human and do absolutely anything to avoid it, crashing into a tree and seriously injuring anyone in the car. I encounter so strange situations on roads, I can't imagine self-driving car being prepared for all of them.
Wow that would be a bad robocar. I've chosen to hit animals, rather than swerving and possibly losing control, on numerous occasions. A robocar that would rather total itself is faulty. Then again a robocar that would choose to kill a child is also faulty. Until they can reliably tell a child from a dog, robocars will not be ready for general use.
That's a high bar. A human driver with a split second to decide may not be able to do that consciously. Maybe robocars should only have to do as well as a human driver?
Manufacturers' liability for lawsuits would seem to require such a high bar? Eventually industry might be able to change the law such that the lives of children in the road are devalued (or perhaps such that animals in the road are valued more highly than car passengers?), but that will take time. Before that happens, a robocar that can't tell the difference just might have to drive real slow.
