It's weird, an optical sensor should fall for this, but LiDAR detects objects in 3D.
Teslas famously don't use lidar because Musk declared that cameras were good enough. Reality disagrees, but reality owns no shares of Tesla.
And then disabled existing lidar sensors in teslas, so his team could just focus on camera vision only
He’s a dumbass
I believe he disabled radar, I'm not sure tesla ever had lidar. Radar would solve this problem anyway.
Yea, to my understanding Tesla does not use LiDAR and that's the issue. They just use cameras I think. Other people posted videos in this thread: https://m.youtube.com/watch?v=IQJL3htsDyQ
I can't be bothered to care/watch anything Tesla related, but apparently the lack of lidar is the thing being tested.
The first ten minutes is him "sneaking" in a small lidar unit to Disneyland be using it to make 3d models of the ride path. That's pretty fun.
Thanks for letting me know. I watched that and ended up watching the rest of the video. It was actually a pretty fun watch.
Elon musk dint want lidar because it cost too much, any tesla before 2018 had it, but it introduced update to brick all off them.
A decent camera only vision system should still be able to detect the wall. I was actually shocked at the fact that Tesla failed this test so egregiously.
If you use two side by side cameras you can determine distance to a feature by calculating the offset in position of the feature between the two camera images. I had always assumed this was how Tesla planned to achieve camera only FSD, but that would make too much sense.

Even if they wanted to avoid any redundant hardware and only go with one camera for each direction, there is still a chance they could've avoided this kind of issue if they used structure through motion, but that's much harder to do if the objects could be moving.
