To play devils advocate, have you ever tried pulling out a map, planning your route, and then driving it? I'm going to assume not based on your response since you'd likely learn the route after 1 or occasionally 2 times of doing that. I say that because I work in an area where GPS directions are usually useless and often have to find my way to a new location based on directions, or by planning my route ahead of time. It works really well.
