Those rules and regulations have helped make cycling ubiquitous and safe in the Netherlands, where 26% of daily trips are by bike. But more than any law, it's that sheer number of cyclists--men and women, kids and the elderly--that really makes the difference. No U.S. city is anywhere near Amsterdam when it comes to pro-cycling policies. (Portland, Ore., where nearly 6% of people commute to work by bike, comes closest.) But as biking gathers speed across the U.S., the out group could become the in group. And maybe poor Jeff Frings will be able to ride in peace.
