Which has been the case in all of Elons endeavours. They usually take twice the time at double the cost, and probably cost some marriages along the way. But he does get publicity and funds it out of his own pocket as far as he can.

A valid point. It's the case with most human endeavors that involve trying something new, I don't think it is unique to Elon's companies.
