> you're assuming that the autonomous vehicle is going to be _better_ than the human

i think this is already proven true empiracally with the existing milage and rates of accidents. https://thedriven.io/2023/04/27/accident-rate-for-tesla-80-l... (or from here https://www.carscoops.com/2023/03/tesla-says-its-autonomous-..., which quotes various sources of data, unless tesla is lying about their FSD data they reported).

Humans just don't believe in autodriving, and there's still the problem of liability assignment - both aren't a technology problem imho, but a human impediment to adoption.
