Tesla uses CV, radar, and ultrasonic. But ultrasonic is just for parking type measurements, up to 36" or so. Tesla did just apply for approval to use 60-64 GH

Tesla uses CV, radar, and ultrasonic. But ultrasonic is just for parking type measurements, up to 36" or so. Tesla did just apply for approval to use 60-64 GHz band for radar, not clear to me how that will change the range/performance they get from the sensors.
