My wife and I were riding north on 7th Avenue, in the left lane in preparation for a left turn on 116th St. A police car came up behind us and announced through the loudspeaker, "Get in the bike lane. Ride in the bike lane, not the traffic lanes." I signaled a left turn and the officer seemed to get it. He may have also noticed the numerous vehicles (including a police car) parked in the bike lane. Clearly the NYPD still does not understand NYC traffic laws.
