I don't think response time is the issue here - at the moment the computer doesn't have the intelligence or ability to learn of the human, so the human is going to be safer in situations the computer was not programmed to handle. I expect we will eventually get human level AI (but maybe not very soon), and if that is used for autopilot then the computer could have the safety edge with faster reaction time if in-car hardware is fast enough.
