Does this mean the problem is more complicated and nuanced than we had originally assumed so that they are constantly going to struggle to program it to even barely match the performance of a human being? I'm still disappointed that the system has to use underlying maps to know where lanes are and what the speed limits are in them. What happens when the map is less than 100% perfect?
