I'm generally hesitant to accuse successful people of being terrible at their own field, but I have long thought that Tesla's reasoning for this made very little sense. Yes it's true that humans manage to drive without lidar, but humans would drive more safely if they did have lidar! Even if Tesla had succeeded at human-level driving AI, there are fundamental limits on sensors that can't see in the dark. The obvious next step would be to make your cars even safer via superhuman perception, so why would you not just include those sensors from the beginning?

tesla's decision to point blank refuse to touch lidar has proven to be one of the most insane self owns of any technology company ever. they easily have the research talent, and waymo has proved they could be doing millions of fully autonomous rides. at this point it's a choice

Wasn't it too expensive back then and now it's too expensive to retrofit every tesla that was promised self driving

Reasonable explanation at the beginning, but they've included new technology in more recent Teslas. Why not do the same with sensors?

A valid approach to design in general, but my point is that the part is clearly necessary for long-term success, even if not needed right away.

i generally agree with your posts but im gonna have to disagree here slightly inflammatory posting on your side > successful people of being terrible at their own field besides that, tesla’s decisions against lidar is consistent with their general beliefs find problem -> find

The current obstacle to level 5 self driving is an intelligence one, not a sensor one, so I don't think lidar would solve it. (As evidenced by the fact that Waymo hasn't solved it either.)

Maybe it's like Palm Pilots -- with stylus -- and Apple iPads without. Two approaches. Let the market figure things out. Is that, in your view, "terrible"? Remember when the Blackberry phone was a thing? Keyboards? On many sorts of tiny little devices? Looking back was

I don't think Tesla's approach should be illegal. I'm saying I think it was a bad business idea, and foreseeable as such even before Waymo attained its current level of success.

heres what I dont like about Lidar: if all the cars on the road use lidar, what prevents them from conflicting with each other? confusing each other? I think Lidar doesnt work if multiple cars in proximity use it at the same time.

Lidar has come down massively in cost recently. And Teslas were originally marketed as a luxury vehicle! They were not at all affordable.

I always found it weird that the guy who is like “human sight is all you need” is also the guy who owns neuralink.

anecdotally, tesla's self driving team was such an absolute mess i turned down further interviews with their team. granted, this was when it was obvious karpathy was about to leave so maybe this pov is unfair. but i will not be getting into a self driving tesla anytime soon

Yes it’s such a stupid argument. If we invented an ultra low cost X-ray tech that let you see around corners, you wouldn’t use it because humans don’t need it?

I think the key piece here that many are missing is that they have spent YEARS claiming that all of their vehicles have sufficient hardware to self-drive. By pivoting to Lidar they would open themselves up to tremendous legal and reputational risk.

Yeah it is very odd. The sensor confusion argument never made any sense either. If i had to guess, it was initially a cost saving thing and now he's just too stubborn to change course.

Considering Tesla has 1000x the autonomous vehicles that Waymo does, I’m confused why you think this is so obvious a trade-off.

1/ $TDUP has solid gross margins. That proves the resale model works. So if the engine works, why is this not a cash machine yet? Because the problem is not pricing. It is structure.

Don’t fall for absurdities like this. A human programmed Claude and thus projected their own anxiety into the computer. AI does not have a soul or consciousness and cannot magically gain such. We will collectively turn into hive mind computers before AI machines turn into us. x.com/polymarket/sta…
