Their LIDAR provider pulled out and now they're switching to camera-based CV and ending development of the LIDAR branch. I think they're hoping that this approach matures enough to match the capability of LIDAR in time for them to meet their market goals.
Either you're confused or I'm confused as to what you're talking about. Tesla has never used LIDAR and they actually leaned more heavily on CV until recently when they started using radar more extensively.
