Re: Who's gonna buy it?
"...the "moral" decision has been made and "we" have decided that if the car has a single occupant and there is a choice between killing..."
Here's the thing - the mechanics involved in a crash are highly complicated, and human beings and their internals are highly complicated. Therefore it's not always possible to anticipate who is going to die / be severely injured. The only thing that can be predicted is impact and speed. Many people have survived horrendous impacts, and many people have died / been severely injured from seemingly trivial collissions.
I tend to agree with what many people have posted already - autonomous braking on a car is already pretty good and the brakes on modern cars are stupendously good. If there is not enough time to bring a car to a stop there is certainly also not time to significantly change direction/target
