Thompson points to significant gains in bicycle commuting in the last decade, which is up 57% since 2000, and finds that "While biking and walking make up 12 percent of all trips in the U.S., they receive only 1.6 percent of federal transportation funding, according to the report. If House Speaker John Boehner & Co. get their way, that percentage would drop to zero."
Thompson also writes about the chicken-and-egg way in which increased biking and walking lead to increased funding and participation in non-motorized transportation. Perhaps more important are the safety implications of increased biking and walking. Cities and states with more biking and walking see far lower fatality rates than places with low levels of bipedalism.
With, "40 percent of all trips in the U.S....less than 2 miles. Clearly, we could be doing a lot more biking and walking, and a lot less driving."
