A LIDAR array is a requirement for automated driving. It can operate in some conditions that radar cannot. lidar, radar and computer vision should all be used in concert for best effect and Tesla knows this, but chooses/chose not to in order to meet a price point. That choice may have been the right one, I don't know. Hacker news (and me too, to be honest) focuses on Tesla, but there are a lot of other players doing this and doing it better IMO.
