See taxis lined up on E42nd by the FDR? They are taking a leak at the park, but beware. The NYPD has been known to creep up on unsuspecting cabbies for parking violations. Same story along the right side of Lexington through Grand Central Station and into the upper 30s (Murray Hill). No pick ups or drop offs allowed. You must do your business along the left (east) side of the Avenue. I know cabdrivers who have been ticketed during sting operations for this offense.
