Today is National Bike to Work Day, an annual campaign to encourage people to consider biking as a viable transportation choice for their commutes. Besides being fun, bicycling saves energy. It produces no new emissions, and burns no fuel other than our own calories.
Currently only 0.6% of U.S. commuters use a bicycle to get to work, and it rises only to 1.0% in the largest cities. Of all trips made by Americans in major cities, 76.7% are by car, despite the fact that 40% of these trips are two miles or less.
