One thing that has impressed me as I've read posts here, looked at Tesla (and other car makers') systems is just how much our brains do and how good they are at it without even 'thinking.' we instantly and subconsciously judge distance with both binocular vision and other depth cues. We keep track of a myriad of different objects and trajectories and plan our own, all while drinking our coffee and eating a burger!Tesla says humans do it with just vision, so cars can too. Well, yeah. Except we humans use binocular vision and parallax to judge distance, as well as other clues. As far as I know, with three forward-facing cameras of different focal lengths, Tesla isn't doing parallax computations.
