>I think self driving cars have already passed the test of "number of crashes" or "number of fatalities" per mile driven.
This is not definitively known. The distribution of conditions under which self driving cars operate is very different from the distribution of human driving. Self driving car miles are disproportionately on the highway, with little traffic, in perfect weather (i.e. by far the safest driving conditions). In addition, we don’t know how many disengagements (or remote interventions) would have resulted in an accident.
True, true. However, if I had to bet... I'd bet in a fully self driving world (using today's tech) there'd be overall far fewer fatal accidents. However there'd also be a lot of bullshit we are simply unwilling to deal with (e.g. cars going 10mph in the rain; slow motion fender benders; car unwilling to turn left; gridlock at intersections; lots of random oddities). I guess my point is that safety metrics are certainly important stats to gauge self driving progress, but certainly not the only metrics that matter, and perhaps not even the most important.
I think that’s underestimating just how bad people are at driving. There is little meaningful difference for other drivers from a bunch of self driving cars suddenly blocking traffic and an actual traffic accident.
People aren’t going to trust cars to safely do level 5 if they can’t do level 4 99.999% of the time. So sure there will be occasional stories of i95 blocked for 3 hours due to software bug, but how is that different from a major accident that occurs regularly?
This is the argument self driving car companies are currently trying to make. My contention is this reason doesn't seem compelling to the general public. For whatever reason the public seems more tolerant of human error than machine error. At this point anyway. I foresee a long period of trust-building before widespread adoption.
An interesting experiment would be for Uber to send two cars for pickup, one human and one self driving. And let people choose.
