Agreed, quite true all around. Elon's optimism and determination reminds me Steve Jobs back in the day, rest his soul. They both can be a bit of a pushy arse at times, but their visions have no doubt brought great things. Regulators would have to do their best, and that also includes people's confidence in wanting to use self-driving tech in the first place. I think 5 years is a good time-frame to see this adoption.
