A full fifth of the city needs a car to get around, and the town is notorious for trapping tourists within its labyrinth of surface roads. Exactly how is this place "convenient"? It's all a matter of perspective. If you're fortunate enough to be in Dupont Circle, Logan Circle, Downtown, Foggy Bottom, Mount Vernon Square or the U Street Corridor, everything you need is within walking distance. Georgetown also tends to be fairly self-sufficient, but even neighborhoods away from the center of the action, such as Friendship Heights and Chevy Chase, tend to be kind to the car-free. They owe a lot of thanks to D.C.'s Metro, which handled 409 million riders on its buses and subways last year and takes a lot of the traffic and tourists off the road to Reagan International by bringing them there directly. A glut of park space and a design heavy on long streets and blocks meant to draw people into its center, though, gives the nation's capital a decided advantage among pedestrians even if some of its intersections seem more pedestrian-perilous than pedestrian-friendly.
