This is why I cringe at self-driving car efforts which depend on extremely high resolution maps, and the companies working on building those maps. Any such map is instantly out of date, so the car needs to have a good enough understanding of its surroundings to be able to ignore the map. Which means either the car is dangerously inadequate, or it doesn't really need the map in the first place. Today's GPS maps are good enough, since a map can only be trusted as a navigation guide anyway.
