Also, Tesla has already done so much for any car manufacturer:
- They have made all patents free to use by anyone. - Elon has stated that he would welcome other car makers to join in on the Tesla Supercharger network if they are willing to contribute in an equal manner.
Seeing as Tesla has more Evs on the road than anyone else by a large magnitude, and they have proven their charging network far more than anybody else, it's odd nobody else wants to join in. But that's Wall Street for you. Nothing will be given away "free", and we can't be seen working with the competition. Despite many of the 'shareholders' are institutions who likely would own shares of both companies regardless. And at the end of the day, Wall Street is a secondary market that should mean jack.
Hell, the only reason other companies are now pushing for EVs so much is because Tesla lit a fire under everyone else and despite Wall Street betting against them (high volume of shorts), Tesla is now the top selling luxury sedan in the U.S. Now everyone else is scrambling. We will see one or two major automotive companies that have been prominent in the last century fall. They will either A. not keep up with the EV world (maybe they receive too much money from the fossil fuel industry) or B. Their tech will not keep up and/or fail and they will lose all their competitiveness.
