I saw the video pop up in my Youtube recommended, but didn't bother watching because I just assumed that any cars tested would be using LIDAR and thus would ignore the fake road just fine. I had no idea Tesla a) was still using basic cameras for this and b) actually had sophisticated enough "self driving" capabilities that this could be tested on them safely.
They are not still using cameras but removed LIDAR and radar from their cars during the chip shortage 2020/21. The story they were telling was "humans don't have LIDAR but can drive cars as well, so the cars also only need 'eyes' like humans".
That statement of him is not entirely wrong. But we humans have a very powerful bio computer that is perfectly tuned to process those visual inputs in realtime. Until a comparable performance is possible, removing LIDAR is very stupid.
Besides that, in the fog and rain tests a human likely would have killed a kid anyway, and why settle for human limitations when you could be safer?
We absolutely should also have lidar or analogous tech as part of a solution here, even if cameras did manage to get to human level safety.
The child dummy was clearly visible through the water in the rain test. Tesla's systems just suck.
Also competent drivers generally know to slow down during rain. Hell I was literally taught to drive some roads like its a speedway and even I drop below the speed limit during the rain if visuals are bad enough, especially first rain pulls oils out of the road makes it slippery and may cause hydroplaning.
