Humans drive using “cameras” (eyes) and no LiDAR, that’s the assumption Tesla is making — that a supercomputer can drive 10x better than humans using the same type of sensor. Nobody really knows yet if that’s true but I get the logic.
LiDAR also is UV/visible spectrum and is blocked by dust/fog/snow/rain so it doesn’t help much in many driving situations..
Anything short of fiercely anti-Tesla gets immediately downvoted here. Just how it goes I guess. I’m not the biggest Tesla fan but hope they succeed on this front, we desperately need driving assistance technology to make the roads safer.
