As ridesharing services like Lyft, Uber and Sidecar become more popular, the San Francisco Cab Driver Association is reporting that nearly one third of San Francisco's licensed taxi drivers have stopped driving taxis and have started to drive for the ridesharing services.Justin Sullivan / Getty Images
