I think the map view is missing a mode view.

Directions has mode because they are very different for car, bike, walking and public transportation.

Map view for biking should be very different from map view for cars as high ways are not usable for bikes and bike paths should be more prominient (while useless for cars).

Ditto for walking that also have different paths.

Using the map for "getting somewhere" is a very different purpose that "seing what's here". They need different modes.
