I understand your point and I acknowledge that TSLA is not for low risk investors. That being said, Tesla is more than just another car maker. They are the clear leader (by a period of years) in the new, large emerging market for EVs. Tesla is also a leader in battery tech and self-driving software. How much is it worth to be the first maker of an autonomous car that could replace Uber drivers?
I will likely be buying a Tesla next year (Model Y). I am not doing it to save Mother Earth or to look cool. I am buying it because it is a superior car over ICE; faster, cheaper and more functional.
I would compare the transition from ICE to EV to the transition from tube televisions to large flat screens. Initially just for the rich, but once the prices came down no one wanted tube televisions anymore and that market collapsed within a couple of years (although my dad still has one in his basement). We are close to that moment for EVs. When it happens, Tesla will likely be the top recipient of those profits.
