Taking another step toward complete indispensability, Google Maps on Tuesday became the first service of its kind to add walking directions. In addition to searches for car and transit travel, pedestrians — and, hell, Segway-ers too — can now find the most direct and flat route from Point A to Point B. The function works for trips up to 6.2 miles long, and recognizes that one-way streets only apply to the car-encased (suckas!). Searchers are advised to “use caution when walking in unfamiliar areas” as the directions, still in beta form, potentially lack information about pedestrian bridges, roads without sidewalks, or impassable intersections — but they’ll only improve from here. Now if Google would just add biking directions, we’d be set.
