I think all of this discussion about whether or not LIDAR or cameras are better misses the point that really matters- Will cameras actually be good enough to get the job done? If they are then it doesn't matter which is better. You can always add additional sensors and get more information, but engineering has always been a cost vs benefit problem. If adding LIDAR doesn't give a significant benefit in scenarios that cameras are not already good enough, then they might not be worth the additional expense.
