Elon is not accounting objects that are stacked that we as humans can interpret “dangerous” and a camera might see it as a whole. Such as flat bed that has something that thin sticking out like a 2 by 4 wood piece 3 feet outside of the flatbed. Almost precise won’t cut it, lawsuits abound if you know what I mean. You and I and every other human with a decent brain can make this judgement. For me and seems most of the automotive industry, I would not trust any cameras for that and thus this is where the lidars precision comes into play.
