The fact that no startup has failed, ever, clearly illustrates your point that thinking about things in great depth, during every business hour, is a perfect safeguard against failure. For my part, I think the hype surrounding driverless cars has gotten way ahead of where the technology actually is. Also, there is a strong undercurrent of "laws which interfere with my product launch are stupid" (cf. Uber, AirBnb) suffusing the valley, and this move by Tesla definitely has an element of that.
You've missed my point. I'm pitting their vast team of dedicated professionals against you as an armchair pundit who doesn't think they've considered liability or accidents.
