These videos on Youtube of cyclists and cycling in NYC do not put cyclists in a good light; it's also a little damning on NYC.
I'm a very good roadie and consider myself very adept at cycling on the roadways (with over 30-years of commuting via bike) and I even opt to cycle on roads in lieu of MUPs -- I actually like it; however, not sure how I'd like cycling in NYC
P.S. The title of the video should be: What NOT to do while Commuting on a Bike.
