TSLA price may be justified in the future IFF they are not "just a car maker". I think with batteries, self-driving, something else?, they have a potential to be "more" than a "dominant car maker" but they are definitely not there yet. Will they ever be in such position? This is a bet some are willing to make. Personally, I invested in them near their IPO price right when Elon joined betting that they will become "the best EV maker". They achieved that. Will they achieve a much bigger bet of being "much more than a carmaker"? I am not yet comfortable making such bet. At least not at this cost.
