A lot of this is confirmation bias at its finest. Not saying you're wrong, but I think it's naive to assume Tesla has some "secret sauce" - there are equally smart and competent people at Tesla competitors. I would bet that the risk and decision making process may be different (incumbents may want higher probability of success to make a bet, while Musk's NPV analysis is different), but again it's naive to assume they don't understand at all what is or isn't possible in manufacturing
