You're mistaken, that was about radar not LIDAR. Telsa cars have no LIDAR. The radars in use have poor angular resolution meaning they can tell if something is moving toward or away from it, but cannot tell where that object is. Since driving down the road will necessarily involve many objects on the side of the road, but the radar apparently can't tell where they are because of it's poor angular resolution, the 'solution' was apparently to filter out everything moving towards the sensor at the car's current speed (e.g, all stationary objects.) It's unclear to me what if any circumstances will cause the emergency breaking system in a Tesla to fire.
