I refuse to believe that Tesla's image-based AI can discern better distance and depth information than LIDAR (even if they're using cameras with calibrated positioning for stereoscopic vision or something) without better sources than "Elon said so."
And I am talking about LIDAR not RADAR, even though RADAR also could be used as yet another sensor in the stack. Using only regular vision is a typical dumb Musk thing; LIDAR was quite a bit more expensive when these self-driving things begun to take hold and Musk didn't want that cost so he went all-in with his own dumb solution of "software will fix it."
