This is the first hit from typing "cycling on NYC streets" into youtube. A visitor takes shots on the bike. Very nice. He seems not disturbed by all the mayhem, especially all the pedestrians who enter the bike lane obliviously.
Most streets in Manhattan are one-way, and the bike lanes are on the left side. It takes getting used to for some people. As you can see, there is a hazard from left-turning motor vehicles. They aren't yet used to the fact that they should yield to the traffic in the lane to the left of them.
