By choosing to ride in NYC, you are accepting a certain amount of risk. For those of us that know what NYC is like, this should come as no surprise. What happened was tragic, but I fail to see how anyone can blame either party. None of us were there.
One of my Aussie mates, Jock (a regular on The Aussie Thread) nearly met a similar fate - he was unable to unclip and fell beneath the wheels of a moving truck. He survived, and still rides and races today. I'm curious about what his thoughts on the subject are.
