Part of the problem is reacting in real-time. The part I'm talking about: Is you can "tell" the car what to expect at this interchange, and still react in real-time to present conditions. You hear all the time about Teslas driving off a ramp or not changing lanes quick enough due to odd paint stripes on the road, and I keep thinking you can see this from space. Why isn't there a database of known "this is a road, this is not a road" that it looks at first before looking at surrounding cameras outside the car? You can see how traffic moves -> from space. Part of these conditions are known well ahead of time on any present day regardless of the weather.
