Hey, so it turns out the all-powerful @BicycleLobby didn't actually scale the Brooklyn Bridge and plant white American flags at the top. That was two all-powerful German artists.
But courtesy of Clarence Eckerson Jr., here's some footage of raw bicyclist power in Copenhagen, where turning drivers defer to people on bikes at intersections. I guess this is what you would call "soft power." So many people bike in Copenhagen that all these polite motorists are probably either cyclists themselves or know close friends and family who bike. Each person on a bike going by could be a neighbor, an aunt, or an old roommate.
