They reference map data for general route planning, and then defer to onboard cameras and other sensors which feed into image-recognition systems to drive in the same way as a human (by paying attention to the environment, and not blindly following GPS).
These cars use cameras, lasers and radar to look for lines on the road (or other markings), road signs, cyclists, pedestrians, other vehicles, etc., and use this to build a live 3-dimensional map of the surrounding area. The software builds a stack of triggers, sorts them according to priority, and then reacts, by turning, braking or accelerating.
