There is a tradeoff here that many have resolved categorically in favor of people being able to override computers. I think only competent and sensible people people, under the right circumstances, should be able to do so. The problem is to find a mechanical system capable of making these distinctions. Maybe a partial solution would be to allow only drivers who have passed courses at high performance driving schools to override. Actually, the first man-made object to land on Mars was a Russian craft that sent about 30 seconds of carrier signal and then died.
Nobody knows exactly what happened to it.
