They'll never do it because it would have to use economic demographics and would be discriminatory.
Microsoft MapPoint has a nice feature where you can "weight" the type of roads. So you can enter a strong preference for freeways, strong dislike for neighborhood streets, and highways as middle ground.
It always gives better route choices. It would be nice if the car had a USB, bluetooth, or IR port so you could upload route information and waypoints from a laptop.
