Rivian has yet to prove it can build cars profitably, and its self-driving effort is far more than two years behind Tesla's, a total dealbreaker. That rebuts @calistoker123's case that R2 is the second-best US EV and that Rivian, at a $23 billion market cap, could deserve $100 billion if it executes on R2, R3 and self-driving. x.comÂ
