Said to save about 10% for delivery vehicles in both time and gas. Thus pays for the system in a year or so. The interesting point was that they had to develop their own maps. No existing available maps were sufficient in accuracy for the system. When installed, the self contained where-am-I system uses wheel sensors most of the time, but corrects by assuming that you mostly drive on the road and turn at corners. It stores its map on (cheap) mag tape, which is fast enough. Amazing, commercial, inexpensive, and with lo-tech data storage.
