On Sunday, thousands of cyclists found out what it's like to enjoy car-free city streets. They were taking part in Bike Philly, an annual ride hosted by the Bicycle Coalition of Greater Philadelphia that includes 10- and 20-mile loops closed off to traffic.
There's no mystery why the coalition includes the "car-free" hook. A recent study shows that even in bike-friendly Portland, Ore., a strong majority are intrigued by urban bicycling but fear for their safety. Not without reason: According to 2009 statistics from the National Highway Traffic Safety Administration, 70 percent of that year's 630 cycling fatalities (15 in Pennsylvania) occurred in urban areas. The vast majority of cyclist deaths are caused by cars.
