SFPD were ticketing bicyclists riding on the sidewalk near the Caltrain station at 4th and King this morning. But they were not ticketing any of the drivers blocking the bike lane, which forces many bicyclists onto the sidewalk.
[...] When I asked if the officers were also enforcing the traffic laws against the taxis and private cars that double park and block the bike lanes leading to the station, forcing people who ride bikes to have to move into the traffic lanes, the officers stated they had been given instructions only to focus on bicyclists.
The bike lanes installed on Townsend Street on the north side of the Caltrain station were ushered in with quite the fanfare, just days after the permanent injunction against bike facilities was lifted in August, 2010. But this morning, like any other typical weekday (according to bike commuters I spoke to), the bike lane was at various times blocked by taxis, a Bud Light delivery truck, a shuttle bus and private automobiles. Some taxi drivers like to make sudden u-turns out of the taxi station, endangering bicyclists riding in the bike lane.
I can tell you from frequent personal experience that 90% of the taxis at that particular taxi stop begin their journey with an illegal u-turn through the bike lane and 4 lanes of traffic. Legality aside, the sidewalk is the safest place for a bicyclist to be, if they value their lives.
