Clif cites research demonstrating that 40 percent of all American urban trips are under 2 miles long, 90 percent of those being by car, and that 60 percent of the pollution created by cars occurs in the first few minutes of operation. The “Two-Mile Challenge” will be traveling to universities and farmers markets all up and down the West Coast this fall in an attempt to reach the next generation of would-be car-dependent commuters to convert them to cyclists who ride all of those 2-mile journeys on human power. Inside of the bus, you can locate your home on a computerized map, which then draws the 2-mile radius around your house and shows businesses within that radius.
