Part of the problem is that he promises things that are a physical impossibility, and those of us who can do basic math say, "You know that's impossible, right?" And then every yells at you for having no imagination. I know a lot of people even within the auto industry who think he shits gold. I am not one of those people. I think the thing he has done effectively is to revive the market for electric cars, which should have a place in the world, albeit not at 100% market share like Europe and China are proposing. I know far, far less about SpaceX and space travel generally than I do about Tesla and the auto industry, so I don't consider myself in a position to evaluate any of his rocket claims. I find it eternally hilarious, however, being a veteran of the manufacturing world, that Tesla seemed to lack any conception that making cars is hard. I'm retired form Tesla bashing, however, so I'll shut up now.
