> why is that not proof of a net benefit? Autonomous vehicles may be more prone to certain types of lethal accidents that humans aren't prone to. Autonomous vehicles may lead to more hours/miles driven, so even if deaths per mile driven are lower, the deaths per person may increase. Unknown physical or cognitive health effects of being a passenger versus being an active driver. Just off the top of my head. Fingers are crossed that autonomous vehicles won't lead to an increase in animal deaths. The roads are bad enough for them as is. I'm hopeful that convoying autonomous vehicles for long trips may be a benefit here.
