"frothy fed money" doesn't explain anything because it doesn't seem to flow to companies that are other than Tesla.

And you're mis-representing what Musk says or thinks. He tweeted, once, "the stock price is too high". That's it. It could have been a joke. It certainly doesn't imply that he doesn't think the value is unwarranted.

As to "but Elon said..." blame game, here's Ford, in 2016, saying they'll have self driving cars in 2021: https://www.nytimes.com/2016/08/17/business/ford-promises-fl...

Tesla just released FSD beta, capable of doing fully intervention-less drives (sometimes).

What does Ford has today?
