San Francisco Ponders: Could Bike Lanes Cause Pollution? - WSJ.com - New York is wooing cyclists with chartreuse bike lanes. Chicago is spending nearly $1 million for double-decker bicycle parking.San Francisco can't even install new bike racks."We're the ones keeping emissions from the air!" shouted Leah Shahum, executive director of the 10,000-strong San Francisco Bicycle Coalition, at a July 21 protest.
WSJ's Phred Dvorak reports from a Critical Mass event in San Francisco, a monthly bike ride that draws hundreds of cyclists. She talks with bikers as well as disgruntled drivers.
