I think the statistics to compare self-driving miles vs human driven miles are quite tough to judge.

Tesla was criticized quite a bit at one point for comparing deaths per Autopilot mile to deaths per all motor vehicle miles. This was a bad comparison because motor vehicles included motorcycles, as well as older, poorly-maintained cars, etc.

Then Tesla released a comparison between Autopilot miles in Teslas and human-driven miles in Teslas where Autopilot was eligible to be engaged. This felt like a much more fair comparison, but Teslas are lenient about where Autopilot can be engaged - just because the car will allow it doesn't mean many people would choose to do so in that location, so there might be some bias towards "easier" locations where Autopilot is actually engaged. There's also the potential issue of Autopilot disengaging, and then being in an accident shortly afterwards.

This is morbid, but I also wonder about the number of suicides by car that are included in the overall auto fatality statistics. If someone has decided to end their life, a car might be the most convenient way (and it might appear accidental after the fact). That would drive up the deaths-per-mile stat for human drivers, but makes it tougher for me to decide which is safer - Autopilot driving or me driving?
