GM is a recent bankrupt and Ford isn’t doing much better, so they are not a good comparison. 100b is half of Toyota’s market cap, so it is anticipating massive success, a little high for Tesla right now, but not a bubble valuation yet IMO. The Uber market cap is explained by a bet on worldwide autonomous taxis, though I think Tesla is better placed to take that market, again it anticipates future success.
