As I'm attending a meeting tonight relating to traffic on the Upper West Side, I thought this anecdote might be informative.
In 1992, I was living in a building on the corner of Columbus Avenue and West 77th Street. One morning, I left to hail a cab at about 5:45 AM. If you're familiar with the neighborhood, you know that at that time, hundreds of cabbies race down Columbus Avenue en masse, at speeds approaching 60 mph., resembling nothing so much as a school of bright yellow sharks in search of prey. (This behavior can also be seen downtown, where Church Street becomes Sixth Avenue.)
Anyway, I extended my hand to hail a cab, and, in their haste to get a fare, three cabbies collided in front of me, doing considerable damage to their cars. I calmly got the next cab, who happened not to be speeding, and left them to their angry recriminations.
