I agree with most of your points however I'm not convinced by your problem number 2: >you should check the autopilot against a rested and concentrated driver that drives slowly and with a lot of care. Since in the statistics otherwise you do not account for the fact that when you drive, you are in control, and you can decide your level of safety. Such a diligent driver that goes to crash because of an immature software is terrible. I think you overestimate the rationality of human beings. I commute to work by motorcycle every day and I've noticed that I tend to ride more dangerously (faster, "dirtier" passes etc...) when I'm tired, which rationally is stupid. I know that but I still instinctively do it, probably because I'm in a rush to get home or because I feel like the adrenaline keeps me awake. This is an advantage of autonomous vehicles, they can be reasonable when I'm not. I expect that few drivers (and especially everyday commuters like me) constantly drive "slowly and with a lot of care". A good enough autonomous vehicle would.
