Robots eat cars
Terr_: > Steer-by-wireThinking back to case-studies around the Therac-25 [0], I would like to pre-emptively highlight the differences between:1. Technique X is unsafe.2. Technique X is unsafe because too much can go wrong even with the best intentions.3. Technique X is unsafe without strong QA and interlocking safety measures, and there's too much economic pressure for the manufacturer to cut corners.[0] https://en.wikipedia.org/wiki/Therac-25
otikik: Cars that nobody buys replaced by robots that nobody buys
cyberax: Moreover, Technique X does not actually provide any significant value.The whole steer-by-wire in CT happened because Musk wanted a yoke as the control system. And a yoke requires progressive steering which is impractical without steer-by-wire.
SrslyJosh: > The Fremont factory lines that built those cars are converting to manufacture Optimus humanoid robots: one million units per year at $20,000 each, with public sales beginning in 2027.Sure, why not? Seems just as likely as Tesla having 1 million robotaxis on the road by the end of 2026. =)
actionfromafar: I heard it will be 100 billion robotaxis on the road by the end of 2026!
rootusrootus: Who is this "nobody" that bought more than half a million Teslas last year?
MK_Dev: Who bought half a million Model S and Model X?
abcde666777: One million robots to be manufactured in a year - one million robots which will likely be obsolete within five years (if that, I wouldn't be surprised if they're dead on arrival).I don't know the figures for Earth's resources and their sustainability, so this may be a naive take, but I'm always left with the impression that these organisations want to speedrun the depletion of the planet.
lmz: More customers for the related Space exploration company.
rconti: steer-by-wire makes safety nannies way easier, eg, the ones that jerk the wheel out of your hands when they decide you're too close to a line on the road.
wat10000: Other models got the yoke but not the steer by wire.
delichon: The best selling car in the world in 2025 was the Tesla Model Y, with a little over 1 million sold. ~350k have been sold in 2026 as of April.
rootusrootus: > does not actually provide any significant valueIf that were true, it would not explain why other manufacturers are headed the same direction. The CT is not the only steer-by-wire vehicle.
michaelt: Vehicles include low-utility features for market positioning all the time.Do buyers need a motorised hood ornament? A tiny vase built into the dashboard? A built-in champagne chiller? Gull wing doors? A spoiler and a 300-horsepower engine?If it boosts sales by giving the vehicle a distinctive character, though, there's a place in the market for that tiny vase.
nickff: The motorized hood ornaments on Rolls Royce vehicles were a solution to the problem of people being injured by, or stealing the (Spirit of Ecstasy) ornaments.https://en.wikipedia.org/wiki/Spirit_of_Ecstasy
paulryanrogers: Assuming they don't starve to death before insert-space-company can get them to the next Goldilocks planet.
c0balt: The next step is just selling tickets to that flight in advance as a preorder. One could call it roadster preorders because of the difficult road ahead
dangus: This article is written with a little bit of a journalist’s misunderstanding of a topic.They seem to have done research but have strung together unrelated subjects due to their lack of expertise in the subjects.As a result it reads more like a summary or recap of vaguely related stories.For example, Tesla’s pivot to robots has nothing to do with their advanced nature of their wiring harnesses, but it’s spoken in the same breath as if to imply that a Tesla Cybertruck (which is a Model Y with paneling literally glued on top) is more similar to a humanoid robot than a Mustang Mach-E.In reality, what has happened is that the Model S and X have been discontinued and they’re the only products the Fremont, CA plant produces. Tesla has literally nothing else they can make in that plant. They either make Optimus robots or shut the plant down.Optimus robot production is a face saving move. Tesla barely needs a fraction of that factory to build robots…it’s a much lower-volume and physically smaller product.I should note that none of that has anything to do with Tesla being great at robotics and seeing it as a better business than automobiles. It has everything to do with competitors catching up and Tesla having insufficient development capability to iterate on those vehicles.Who in the buyer demographic for a Model S wouldn’t take a Porsche Taycan, AUD A6 Sportback, or Lucid Air over that vehicle?Who in the buyer demographic for the Model X won’t take a Kia EV9, Lucid Gravity, or Volvo EX-90?Maybe if you aren’t paying attention to the car industry you’ll disagree with me but the problem here is the Model S and X are positively ancient with about zero dollars spent on keeping them updated and they’ve become completely irrelevant to the market as a result.
someothherguyy: > Tesla Cybertruck (which is a Model Y with paneling literally glued on top)Doesn't seem true?
ericd: > Who in the buyer demographic for a Model S wouldn’t take a Porsche Taycan, AUD A6 Sportback, or Lucid Air over that vehicle?I guess me. I have a friend who drives a Taycan, one of the sportier variants with 4 wheel steering and blistering acceleration, and it’s nice, but it’s clear that they’re still crap at computers and interfaces, and I just really don’t want to go back to traditional car industry software interfaces and feature sets after our Tesla. I doubly don’t want to deal with a dealership ever again. Also, love their mobile service which comes to our garage and fixed a flat on two different occasions while I was working at home, super convenient. Roadside assistance was great when we got a flat in the middle of nowhere with no shops open anywhere nearby, they coordinated getting a tow truck out to us to tow it to a Costco like 40 miles away, gratis. Also, it’s just been a great car for us, extremely practical, great for long road trips, fun to drive, the autopilot works well and makes long drives much more pleasant, especially traffic. I don’t know why people confidently declare them to be bad cars - our experience hasn’t been flawless, but as a total package, it’s been the best car ownership experience I’ve had, including Acura, Toyota, Subaru, BMW, Nissans. I guess some combination of not liking Elon, and the issues from the scale-up period when they were making model 3s in tents, though those are long gone.
someothherguyy: who tracks such things? how many companies sell cars worldwide?
