San Franciscans may take it for granted, but to most Americans, the volume of bike traffic on Market Street resembles a Critical Mass ride more than a weekday rush hour. SF's main thoroughfare regularly sees more than 3,000 people ride by the bike counter on weekdays at Market and Eighth Streets -- and that's just in one direction. It may still be a ways away from matching Copenhagen's busiest streets, and it doesn't have raised bike lanes yet, but it's definitely one of the highest concentrations of bike commuters you can find in this country.
