I didn't exactly say that. But I think you and others are underestimating our collective skills. We make stupid decisions, get tired, etc., but we manage to recover, workaround others' mistakes, etc. I think people are underestimating how hard it will be to get "the last 10%" of driving skill, that gap between slapping together cruise control+camera+radar+GPS to be able to handle the best-case scenarios, and being able to drive at least as well as the average human in the average-case scenarios. Another thought: what if it takes a generation or longer for self-driving cars to do well with cases like slippery rain or ice? People will stop practicing how to drive at all, until suddenly one day they have to drive in the most dangerous conditions possible. Will the net cost/casualties of accidents still be lower than it is today?
