No, he precisely said that the difference Lidar made was tested, and the delta (difference made) was quite small; not enough to outweigh the downsides. Elon has noted that humans do well, and that's relevant, but that observation was also tested, re lidar.
- NBJack 4y agoBasically everything he said as a justification (sourcing, firmware, etc.) applies to every sufficiently advanced part of the vehicle. By that logic, they should not be using touchscreens on the center console, etc.
- Nomentatus 4y agoIf the safety delta was low after removing them, as 'tis with Lidar, absolutely.
- paulryanrogers 4y agoIt's also possible their LIDAR implementation was poor. Waymo uses LIDAR and has fewer incidents per mile.
- Nomentatus 4y agoGood point. I'm pretty sure it was poorer, Waymo really goes all-in on Lidar, they still top-mount it don't they? Waymo is also solving a much more constrained problem, with far fewer vehicles, so fewer accidents doesn't surprise me.
- freejazz 4y agoThey are doing exactly what Tesla isn't willing to do and are being responsible in exactly the way Tesla isn't.
- Nomentatus 4y agoBut it's an expensive dead-end for most purposes, esp re the insane mapping. Ok for city robo-taxis. Doesn't solve the real problem to be solved.
- freejazz 4y agoCars drive in cities, last I checked.
- Nomentatus 4y agoI guess you're saying that "cities are mapped, dude." But not mapped in anything like the way Waymo maps for this purpose: if I heard right, yesterday, mapped to the centimeter and very frequently updated to deal with any changes of any kind!
- freejazz 4y agoDriving in cities is a real problem that will really need to be solved.
- gibolt 4y agoWaymo has HD maps that require regular 'trawling', just like Google Street view. They are also very conservative in turns, generally avoiding unprotected lefts. They also are much less human-like.
- croes 4y ago>and the delta (difference made) was quite small But why. Because LIDAR doesn't help much in general or because the Tesla engineers aren't good at using the sensor data? Same with the manufacturing. Sounds to me like Tesla can't handle complexity. And if they can't handle the complexity of manufacturing, they surely can't handle the complexity of full autonomous driving.
- Nomentatus 4y agoI don't think interpreting the lidar data and integrating it is a super-tough problem, it kinda comes in 3D, unlike stereoscopic vision. So I take it this means that the Lidar data rarely differed and it rarely mattered when it did. Elon's companies have a long history of handling complexity very well (even, you know, actual rocket science) precisely because they relentlessly simplify everything they can. Raptor one is more complex that Raptor two, but I'll take the latter any day. Nobody else has a full-flow rocket engine. Many previous attempts were swallowed by the complexity of the task. Even Raptor one looks like a rat's nest - but unlike other attempts, it worked. Tesla's manufacturing margins are far out in front of any other car company (see David Lee On Investing podcast.) Having simpler, larger parts made by much larger pressing machinery is a big part of why. Looks like they are (now) handling the complexity of manufacturing very well.
