At the same time, if Musk went away, the stock would crash back to reality but a non-idiot leader could just do impossible, crazy, hard stuff, like ... working on obvious new models and basic steady improvements.
Tesla PE is 398 today (after a drop). Toyota's PE is 13. Toyota at the least is not hemoraging market share, sales, revenue, profits. Tesla is losing on all thoes things. Tesla would need a 30x price reduction to get down to much much more stable and profitable toyota. It's gets worse because Tesla's sales and profit keep going down each quarter.
There's no doubt value in self driving but the overall value is questionable. If there are many companies providing it, and at least waymo is doing great, plus there are many many other companies in China in good shape, the value multiple won't be there.
What's the market value of all taxi compannies combined in the us? It was about $230 billion in 2024 (https://www.skyquestt.com/report/taxi-market). Will tesla get 100% of the us self driving business in the future? No, waymo at least will be a serious market competitor, tesla's service doesn't really work.
Because there are going to be muiltiple competitors with working products (we'll see if/when tesla ever gets there), Tesla's huge valuation will never make sense. Robots are much farther behind than robotaxis (there's no brain, no prototype of a learning system, maybe one day).
This got way too long, I think GM just saw it as a money sink. I think that was a big mistake, though.
That said, you could be right! Maybe self-driving will never be worth more than that. It's really hard to tell what business models will be like in the future. But this is the cultural mismatch, it seemed like GM leadership did not want to be in a risky business where they were betting billions of dollars on the success of self-driving. Clearly, to some people, that seemed like a really good bet to make. Time will tell.
