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 &quot;laws which interfere with my product launch are stupid&quot; (cf. Uber, AirBnb) suffusing the valley, and this move by Tesla definitely has an element of that.
