> I’m convinced they ditched radar because they were having big supply chain constraints with radar, and then Musk convinced himself that Machine Vision with AI is the path forward anyway and decided to rip the bandaid off and address both issues at the same time. Yes, that and his attitudes towards LIDAR seem like motivated reasoning / sour grapes. "LIDAR is too expensive to put in cars I'm selling today, therefore it isn't good anyway." (I can't reach the grapes, therefore they're sour and I didn't want them anyway.) Why else would he criticize LIDAR with inane arguments about LIDAR not being able to read street signs, as though anybody is suggesting LIDAR-only rather than LIDAR+Optical?
