This isn't to say that the NTSB is thinking about banning or limiting self-driving car tech, assuming it calls for any changes once its investigation is over. As Bloomberg notes, the board has long asked for more automation, since it can prevent collisions that humans would make. However, there's a real chance that it might ask for widespread use of advanced sensors (such as lidar), stricter testing methods or other approaches that could minimize the chances of a crash.
