San Jose Cyclist spots unusual San Francisco Bumper Sticker

Frequent Guadalupe River Trail user Eloy spotted an unusual bumper sticker on a San Francisco cab yesterday. While driving near the San Jose Airport. Eloy took a picture of the unsual bumper sticker but apologizes for not getting a better shot before the light changed. As he stated in an email to me. "Could not get a better pic before the light changed, but the SF cab (in San Jose!!) was sporting a blue bumper sticker stating it had the right to enter the bike lane"

On closer inspection (see below) the sticker reads..."This vehicle authorized to enter bike lane when necessary. Picture shows an open taxi door with a person exiting with a cane.

Has anyone else out there seen a sticker like this on San Francisco cabs.I'm not sure if this is ligit.
