The New York Times ran a good story about the importance of maps to self-driving cars, and the relatively few companies that build them.

Digital maps ease the burden by helping give foresight to a car’s computers, and adding redundancy to the car’s understanding of the situation it faces, said Civil Maps’ chief executive, Sravan Puttagunta. Radar and cameras cannot always recognize a stop sign if pedestrians are standing in the way or the sign has been knocked down, he explained.
