“Imagine walking to a sidewalk corner and finding a public bicycle. With a cell phone call or swipe of a card, you unlock it from its bike rack and ride it across town. Once at your destination, you steer to the closest bike rack and, with one more call or card swipe, return the bike to the public network. You pay less than US$0.50 for the trip, and the bike is once again available for the taking.” Via City Room.
