Tesla has never used LIDAR. New Tesla's don't have radar either. But pre 2021 Tesla's use radar to measure the distance to moving objects. But the radar is fairly wide angle and for that reason items that are not moving are excluded from consideration because they can be billboards or buildings beside the road. This limitation also applies to radar use by other manufacturers for emergency braking sensors.
