Second there is the fact that cars that are self driving will still crash at launch. I see this a bit like air travel where over time every kink in the software will be filtered out. The software will be safer than human drivers at launch so I’m not extremely concerned.
Finally, I guess, will people believe in the statistics or will they go with their beliefs. I don’t know but I’m sure this will happen in the next few years for Tesla and for non highway driving it will be extremely safe. N of one incidents (of real self driving) will probably still happen but as long as what went wrong is learnable from I think it’s acceptable.
