My view is that a properly programmed car is fairly safe. A properly alert human is fairly safe.
But expecting a human to remain alert and aware while a computer is "driving" is insane.
It's the combination that is dangerous- and will just get worse. People will naturally be hugely careful the first time they try one of these, and then get more and more blade about it. So the best stats we have, will be the first. Whoever wants this is perhaps more into tech, than people...
