Also of note: Tesla often claims that their cars perform very well in an accident. It may be that a crash that would result in a fatality in the median vehicle on the road does not produce a fatality in a Tesla. So the salient number is not "fatalities per vehicle mile among all vehicles in the US," it is "fatalities per vehicle mile among non-autopilot-driven Teslas."
