"While Waymo is now providing over 150,000 autonomous rides every week, Tesla still has a long way to go until its controversial “Full Self-Driving” software is ready for the EV maker’s competing robotaxi service.
Just this week, a Tesla driver plowed through a deer without even a hint of slowing down with the $8,000 add-on feature turned on, and another smashed into someone else’s car when its owner employed its Summon feature."…

Musk: “We’ve spared no expense!”
Critics: “So, LiDAR?”
Musk: “We’ve spared some expense!”
I once worked for a big corporation that makes hydraulic rescue tools, where management somehow failed to grasp that the chief selling point of these tools is that they do the job reliably every time. No firefighter wants to be trying to get someone out of a car like, “Damnit! The cutter is acting up again. We should probably look into that.”
But the executives kept demanding that we add “features” to the tools that effectively compromised the reliability and then got all surprised Pikachu face when it was explained to them that the customers thought the tools were overpriced half-assed garbage.
I guess my point is I’ve seen plenty of incredibly stupid examples of management ignoring the engineers and yet somehow Musk demanding that radar be scrapped in favor of cameras is right at the top of the list. Especially if you want your customers to live long enough to buy your products more than once.
Even worse, LIDAR isn’t even that expensive. Musky just thought they should be able to do without it because, “humans do it with just eyes.”
Not a fan of Musk at all, but Lidar is quite expensive. A 64 line lidar with 100m+ range was about 30k+ a few years ago (not sure how prices have changed now). The long range lidar on the top of the Waymo car is probably even higher resolution than this. It’s likely that the sensor suite + compute platform on the waymo car costs way more than the actual Jaguar base vehicle itself, though waymo manufactures it’s own lidars. I think it would have been impossible to keep the costs of Teslas within the general public’s reach if they had done that. Of course, deploying a self driving/L2+ solution without this sensor fidelity is also questionable.
I agree that perception models will not be able deal with this well for a while. They are just not good enough at estimating depth information. That being said, a few other companies also attempted “vision-only” solutions. TuSimple (the autonomous trucking company) argued at some point that lidar didn’t offer enough range for their solution since semi trucks need a lot more time to slow down/react to events ahead because of their massive inertia.
Just so no one mistakes the above as hyperbolic, musk actually said this during an engineering meeting. His engineers kept telling him why Tesla needed the extra sensors, and he replied “people just have eyes and they can drive.”
Anytime someone tries to play him off an engineer or anything but a lucky gambler and flim flam man, just remember the above.
and he replied “people just have eyes and they can drive.”
People also have a brain. Most of them even use it when driving.
Most
Ah, an optimist!
Absolutely.
"LIDAR isn’t even that expensive.
Even my cheap chinese vacuum cleaner has it.
More money tho.
