Elon Musk reaffirms Tesla's commitment to "full end-to-end vision" for autonomous driving, arguing that LiDAR is an unnecessary technical debt for vehicles despite its utility in Dragon spacecraft docking. The post suggests that Tesla's removal of radar and ultrasonic sensors in favor of pure vision has accelerated its ability to handle edge cases, while competitors like Waymo remain restricted by geofencing. The sentiment is strongly bearish on LiDAR as a long-term solution for automotive autonomy, labeling it a "certified hack" compared to neural network-based cognition.
