Lived in NYC for about four years and never saw a cyclist being ticketed or even stopped. Even that guy that killed a pedestrian in Central Park wasn't ticketed, AFAIK.

Only saw maybe four drivers get tickets, though, and two looked more like some dispute about taxi regulations than actual moving violations.

I will say that NYC bicyclists are far more law-abiding and respectful than my current "bike-friendly" city. (Never thought I'd type those words...)
