Superbikeway: Which would you prefer: 40 minutes of inching along in bumper-to-bumper traffic or a 40 minute car-free commute where the only other commuters are fellow bicyclists? In Denmark, a new 11-mile stretch of a paved superhighway leading into Copenhagen is open only for bikes. The route, which opened in April, is the first of 26 supercycle paths like it that will lead into the capital from outlying suburbs. Bike on!
