I found this to be impressive because it seems to be working without LIDAR and performing very well. I may be wrong but most other contemporary cars that drive this well use expensive laser sensors
Lidar sounds great, but 250 meters x 360 degrees without a tower on top of your car sounds cost prohibitive for now.
Cameras are cheap and I suspect the 12 cameras have overlap to help with depth perception and maybe even fault tolerances. I suspect as soon as LIDAR becomes a better solution for the price (if that happens) that Tesla will use them. Or maybe a hybrid of both so they can use the strengths of both as needed.
