I’d say Tesla’s charging network remains a very strong suit for them. Problem is it’s nowhere near strong enough to justify their current valuation. But we’ve been saying this for years and the stock price still stays irrationally high.

Do you ever see any legacy American car companies getting close to what Tesla can do, even with a 10yr timeline?

Well it depends on what you are saying "can do". Ford and GM already outsell Tesla on volume by 4-5x each. There is some portion of the population that will spend more for an EV but that is a tapped and declining market. Chinese manufacturers are selling attractive EVs at a cost lower than their ICE counterpart - not higher. But they are cut out of the USA market. Now we can say that Tesla is leading in autopilot and other things like that but apparently that is not translating to growing sales. They have a stagnant lineup of models that people would actually buy.
