The whole thing is largely probabilistic in many ways/parts, and it seems like more sensors, especially more sensors that operate in different modalities, is better, assuming your sensor fusion is working properly so that each additional sensor adds certainty to your predictions. There are atmospheric conditions and obstructions that lidar can see through that cameras can't. Cameras also seem prone to being blocked by a small splash of mud/dirt. Is anyone on this thread knowledgeable enough in the domain to know if that's an issue? I thought of it while moving my head sideways to see around a temporary sight obstruction on my windshield. Luckily the windshield is big, and I can move my head. Cameras are small. I guess you just put several so you have an effectively large camera array? It does mean more redundancy is necessary than I would have initially thought.
