Our happy hour fact to amaze your drinking buddies with.

Up to 75 percent of bike riders in New York City break traffic and safety laws.

Sociology students at Hunter College in New York City observed 5,000 bicyclists on Manhattan's streets and avenues. They found that 62 percent failed to properly obey red lights, 30 percent didn't use the bike lane when one was designated and 17 percent were spotted going the wrong way on one-way streets.

The students also uncovered that 75 percent of nighttime riders weren't equipped with the proper headlights and reflectors required by law.

Before you start advocating running over these two-wheeled nuisances, remember, this is NYC -- where probably 100 percent of pedestrians violate the rules of the road.
