Is it possible that a company sues their own ceo? Has something like this ever happend?

Can they do that when they just gave him a multi-billion-dollar payday earlier this year?

And yet Tesla stock keeps going up. Make no sense at all to me. P/E is now 306.

Electric car buyers prefer a product out of China with an unknown track record over the devil they know.

I expect Tesla sales in Europe will never recover.

I would guess that it is because of stale line up. There is Model 3, Model Y (which is Model 3 Wagon if that would be a European car) and now they come with a light facelift of Model Y. Model S and X are abandoned.

Compare it to European and Chinese brands, which are offering much wider range of cars and in case of European brands you don't need to travel to a different country to get your car fixed if it breaks.

Tesla worked as long as it had a technological advantage on its competitors (and when its competitors didn't exist at all). Now that the technology went mainstream and the competition is Chinese (high tech & high quality, much cheaper) there is no reason for consumers to choose an American brand. Also, Musk (at least the one that started Tesla and SpaceX, don't know now) isn't someone who's interested in competing in a mature market. I guess that's also the reason for pivoting to humanoid robots: gives him the type of extreme stimulus he needs to keep going.
