But I cannot help thinking that this perception technology will prove very useful for robotics in general, factory, home, in space, etc. Car dynamics are fast enough to be useful across a huge number of domains.\n\nIn some sense, the visionaries in this space are not thinking big enough. I want visions of mobility with a totally different size, look, speed, etc. autonomous Golf carts? tuktuks? A moving autonomous bicycle carrier? etc\n\nLike imagine a low speed, electric, autonomous, golf-cart-only lane at every train station, for the last mile.\n\nThe lead that Waymo has acquired in perceiving its driverless car's environment will be almost impossible to kill. In about 5 years, it'll be like NVidia and CUDA. Tesla's choice to abandon lidar will be one of the biggest oof in business history."

The very core of their strategy was (and is) to sell $40k car with hardware capable of running FSD.\n\nCameras are super cheap, FSD chip is reasonably inexpensive. Lidar is not. Maybe today the cost isn't completely prohibitive (I think it still is, because you need multiple lidars) but it certainly was for the first 8 years of FSD program.\n\nTesla just didn't have the luxury of adding $50k to the cost of the car for the hardware, the way Waymo did. And they didn't have sugar daddy (Google) willing to burn several billions a year for many years.\n\nSo the Waymo approach was not an option for Tesla.\n\nAnd given that in Austin they just reached parity with Waymo (i.e. completely unsupervised robotaxi service), they are not doing badly."

Anyone shooting for the moon (that's not seemingly immune to market pressures) has had those grand visions beaten down by the whiplash of funding. Companies have responded by focusing on those those first, real steps to demonstrate the \"easy\" stuff. The experimental stuff will come later when they're looking for ways to expand and investor money is more confident in the technology's future."

If Cruise were actually a third viable competitor in this race, it would probably be worth more than the rest of GM. Self-driving is just a far more valuable business than car-making.\n\nSo from that point of view it would make sense to say, don't worry about the rest of GM too much, you should be willing to sacrifice all of that to increase the changes of making Cruise work.\n\nIt's hard to change the culture at a place like GM though. Does the GM CEO really want to take a huge amount of risk? Would they be willing to take a 50-50 shot where they either 10x the company's value or lose it all? Or would they prefer to pay a few billion dollars to avoid that risk."

"text": "Using tesla valuation is not useful. It's a meme stock, has AI bs overvaluation over it. It's value is completely unconnected from reality. The car business is declining steadily. It's a good day when the famous CEO doesn't do something incredibly destructive to the brand name. It's just going down.\n\nAt 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.\n\nTesla 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.\n\nThere'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.\n\nWhat'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.\n\nBecause 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).\n\nThis got way too long, I think GM just saw it as a money sink. I think that was a big mistake, though."

The market value of all taxi companies combined was pretty small when Uber started.\n\nThat 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."
