I think there's some chance that Tesla's approach will work out for them, but I'm not optimistic. Getting self-driving software to "impressively good" happened pretty quickly, and even systems from 2016 would usually pass your "go there without touching the wheel or pedals" test. But from there to "as safe as a human" let alone "as safe as we require human-replacing machines to be" turns out to be quite a hard gap to cross.
