It has a radar, but it is 1-D and low resolution.  It uses this to localize other moving cars.  In theory, it could use this to see a highway divider or firetruck it&amp;#x27;s about to hit, but since it&amp;#x27;s 1-D that would also mean that it would have to slam on the brakes when it sees an overpass coming up, because it can&amp;#x27;t tell the difference between an overpass and a highway divider or a firetruck.  It can assume that overpasses aren&amp;#x27;t driving at 60mph, so it will see other cars.  The Tesla algorithm is &amp;quot;look for lane markings and try to stay between them, and don&amp;#x27;t hit any moving vehicles.  If there is any stationary object, including another a vehicle in your lane, the &amp;quot;Autopilot&amp;quot; will plow right into it.

If it doesn&amp;#x27;t measure height, then it would still be 2-D.&lt;p&gt;EDIT: it&amp;#x27;s a 1-D array of distances, ie, an array of polar coordinates on the 2-D plane. So, it&amp;#x27;s 2-D data.</text></comment>
