Pedal Power.
Pedal Power.

The number of U.S. bicycle lanes separated from traffic has almost doubled since 2011, with almost 150 tracks keeping two-wheeled pedalers safe from their four-wheeled competitors, and another 200 projects planned, according to Boulder, Colorado-based PeopleForBikes. London Mayor Boris Johnson, meanwhile, this week announced plans for a segregated bike lane at one of the city's most dangerous junctions, to protect the 3,000 cyclists who cross Vauxhall Bridge during rush hour each day.

So the Trade of the Day is to buy a bike. As George Orwell almost said: Two wheels good, four wheels bad.
