Poor, unloved TSLA with 1% of global sales and 50% of global market cap

Rivian could grow 100x, Tesla won't. Rivian is a pure EV play that won't neglect new vehicle R&D in favor of humanoid robots. Rivian has a CEO who doesn't publicly promote right-wing conspiracies. Or make absurd claims about self-driving. Or whine about his customer/investors being to dense to understand how important his humanoid robot will be. Lots of reasons why someone might invest in RIVN as well as or instead of TSLA.
Furthermore, RIVN was down more than 80% from their 12 month high. They've been severely punished for missing guidance, and the stock price weighed a high risk of further misses against that massive potential upside. There's naturally a sigh of relief when they showed good progress on the ramp and affirmed full year guidance.
That said, I'll need to see a path to positive gross margin before I even consider RIVN as a speculation.
