If the market were rational that would have been the end of Tesla. It takes some extreme brainletry to turn a huge market advantage into actively losing ground to new entrants. And he is still at it. Being a dimwitted Nazi on Twitter is his top priority. Tesla sales will continue to spiral down the drain.
(Yes, if the market were rational the end might have come sooner, but certainly giving billions to a brainlet actively sabotaging the company should end it.)
