What would get Americans biking to work?

Bike parking, in both commercial and residential areas, is essential. From Slate: http://www.slate.com/id/2225511/

Donald Shoup, author of The High Cost of Free Parking, has estimated that 99 percent of car trips in the United States terminate in a free parking space, which means the nation's drivers don't have much incentive to think about parking—or not driving. In many American places, there are more parking spaces than people.

If car parking is often overshadowed in traffic talk, bicycle parking is even more obscure. For many people in the United States it might be hard to imagine what there is to talk about. Why don't you just stick it in the garage? Or: Isn't that what street signs and trees are for? But as the share of trips made by bicycle has grown in recent years—in Portland, Ore., for example, bicycle use has grown nearly 150 percent since 1990, and an estimated 5 percent of people bike to work—new attention is being paid to what happens to those bicycles when they are not in motion.
