  That's terrible performance. The problem seems to be that Tesla's system is extremely dependent on a nice clear white line at the outer edge of the road. On this road, near the traffic islands, the roadside grass sometimes overgrows the road edge and obscures the white line. The white line has also been scuffed by cars near the edge of the road. [1] The Tesla runs off the road in that situation. There are two kinds of self-driving. One came up from the DARPA Grand Challenge, which was off-road. That kind first looks at the terrain and obstacles, and figures out where it can physically drive safely. There's LIDAR profiling of terrain. Then it looks at road markings and figures out where it's supposed to go. If the road markings lead into an obstacle or drop-off, it will stop or go around the obstacle. That's Waymo. The second kind came up from lane-keeping and auto-brake systems. Those are very dependent on highway markings, and only work right on freeways. That's Tesla's original system. It's hard to tell about the others. Volvo has an extensive sensor suite. Otto seems to be mostly a lane-keeping system for freeways. Uber hasn't released much detail.
