> Andrej Karpathy addressed this point in his recent Lex Fridman interview - more sensors aren't necessarily better, and for each sensor you introduce a whole host of supply chain issues and physical constraints. That's a bullshit justification. Going to camera-only and trying to overcome that limitation with "AI" was hubris. All of the competition working on FSD realized cars need more and more varied sensors, not fewer. Humans use a variety of sensors between primary perception and proprioception to drive vehicles. The biggest problem with camera-only is the system needs to recognize objects to understand them as road hazards. Humans don't need to recognize a thing in the road to think "don't hit that thing". It doesn't matter is an object in the road is a crumpled newspaper, a cinder block, or a cinder block covered in a newspaper, you avoid it all the same. Vision augmented with radar and LiDAR can help just say "that's a thing in the way" more reliably than vision alone. Glints from the setting Sun or windows aren't going to cause radar to think some solid object is no longer a solid object. A bad angle or odd shadow won't cause LiDAR not be able to pull an object from the background.
