Just commenting about the "one crash will kill the industry" part - I've heard this repeated many times over the last 20 years (way before self-driving cars were close to viable). I've repeated it myself.

But it looks like we're wrong. First of all, there have been crashes with even Tesla's autopilot, and it didn't seem to affect anything.

For another, this same logic would've probably meant that driving itself would never have become popular in the first place, or would've been set back many decades because of car crashes. That doesn't seem to have been the case.

I'm not saying these things can't kill an industry, but I think people are pretty tolerant of even unthinkable dangers beforehand, if the incentive is high enough.
