The genius of Tesla was that it offered EVs before anybody else took it seriously (and this was happening far before Musk ever came along).

But under Musk's leadership, all they had were unrealistic ambitions and empty promises. The quality started suffering. Deadlines weren't met. Blah blah blah.

The other manufacturers are slow to the game, but they're going to offer quality EVs for a hell of a lot less than Tesla does. I would even venture to say that it's not too late for Tesla to stay on top of the EV game, but it's not going to happen because Elon would ride a sinking ship all the way down before actually listening to the intelligent people who know how to run companies.
