If Elon leaves, Tesla is cooked. Tesla nosedives every time his focus is on something else which is what's happened since he purchased Twitter, became a political activist and then left to work with Trump. The only reason Tesla trades at such high valuation is because of Elon and the cult following he built around the vision for the company. As soon as he's out of there the stock will lose all of its premium. Institutional investors like Ron Baron who are open supporters of Elon's vision will leave and the business will go to carmaker-like or negative margins. There is absolutely no evidence that Tesla can function at all without Elon but there is plenty of it floundering when he's not focused on it.
