The market cap exists because Musk has lobbied the government to not allow Chinese cars that are way cheaper and have better Quality Control. So most people have to purchase one of his electric lock only, semi-trucks-are-the-sky death boxes. They will always have problems because they are always parsing raw video data since they use such cheap cameras. You can believe what you want, but Musk sits on a cardboard throne that he did not even earn by legitimate means. Tesla is not a superior product, its one of the only products allowed in town.
