In NYC, the bike lane is the "kill zone" for double parked cars and opening doors. I always try to avoid it, unless its one of the (few) good ones that is actually blocked off from traffic. Because cops are always "pulling over" into a double-parked position (as in not parking on the curb), they tend to infringe on this space by default...Same with taxi's pulling over to pick up fares...and pedestrians trying to flag a cab as well...not to mention the delivery guys going the wrong way...etc...a veritable obstacle course
