Maillot Jaune: Bicycles can save the economy. According to the national building museum (see below), the reduction in car ownership in the District (15,000 fewer cars despite 15862 more residents) between 2005-2009 kept $127 million dollars from leaving the District. That will buy a lot of bike lanes.
Maillot Vert: But that is only part of the savings. "Now, some of Gotschi’s calculations are probably a bit of a stretch from a purely scientific point of view. But his main point — that during the next 30 years Portland residents could save as much as $594 million in health care costs because of the city’s investment in biking — bears noting. The more we spend on bike lanes and other biking inducements, Gotschi says, the more the eventual health care savings." I'd love to see a plot of major American cities, with the x-axis being "money invested per capita" since 2000 and the y-axis as "increase in bike commuting" over the same period. You'd expect a somewhat direct relationship, but one researcher they interviewed questioned that.
Maillot a Pois Rouge: Chicago is testing cycletracks. "The Chicago Department of Transportation was given a $3.2 million grant from the federal government to improve their bicycle lanes by testing and building cycle tracks in the city." They also did a bicycle count and determined that mode share at one place was as high as 21.9%.
Maillot Blanc: LA's bicycle plan, which should be approved by the City Council, calls for 1680 miles of bikeway.
Lanterne Rouge: The driver in Brazil who plowed through a Critical Mass ride is being charged with attempted murder.
