Currently, if you use MapQuest, it’ll tell you the best way for a car to get from point a to point b. But with FootQuest, or whatever it’ll end up being called, a pedestrian might be able to cut across a park, go the wrong way up a one way street, take a foot bridge, or even head across a campus or a mall. There’s no speed benefit to a pedestrian for following a major street instead of one a block off a major thoroughfare, and the air’s a lot cleaner when you’re not taking the route dominated by cars.
