> “Historically human beings have shown zero tolerance for injury or death caused by flaws in a machine,” Pratt said. “As wonderful as AI is, AI systems are inevitably flawed… We’re not even close to Level 5. It’ll take many years and many more miles, in simulated and real world testing, to achieve the perfection required for level 5 autonomy.”

I can believe that, but I also disagree that we need to be there for it to be useful. Level 4 is enough for large scale deployments.

I think it's far more likely that there would be a three step process for this technology to be adopted: first it's early adopters and everyone else is like "whoa that's too far" (I think this has already happened), then people start to uneasily use it, and when it's good enough they realize "oh holy crap, the machine can drive while I watch Netflix! this is awesome" and then they'll use it constantly. Soon, it just blends into the background. Maybe it isn't 100% safe, but what is?

I don't think you'll get the truth out of focus groups, either. Try to hold a focus group on self driving car adoption and 99% of the people will tell you "only when it's perfect." Probably if you ask the same focus group if they text/eat/put on makeup and drive, 99% of them would tell you "absolutely not" when I'm sure that 100% of them do. I think that once a somewhat good enough assist gets into peoples hands, it won't stop.
