It would also help with some roads that are incorrectly marked on the GPS. There is a highway in ND that has a 4 mile stretch that has a miss marked road. Multiple GPS maps show the road about 100 yards west of where it actually is. Damn annoying driving 4 miles with the GPS constantly saying "Get back on the road". Thought it was just a garbage GPS map, but it happened on a couple of models.

Guess I really don't have to worry until they figure out how to get the car to drive on snow covered roads.
