Ditto! Seeing those NYC cycling videos sure brings back memories. And yes, it is a city of whackos but also lot of excellent human beings as well. It's just a high concentration of humans squished together at times, who for the most part are just trying to get by.
When I lived there 30 years ago, it seemed the rudest people were the commuters who lived in the suburbs, rushed in, rushed around and rushed out of the city at the end of the day. After hours, it was a different cadence. Dead quiet, nearly deserted in mid-town, and people restaurant-hopping and clubbing on the West Side, Theater District, Chelsea, the Village and SoHo... great places.
I loved riding my bike, even in the rain. It was better to ride in the street during rush hour than the sidewalks, because they were jammed with people, I sometimes got off and walked my bike through some intersections because it was faster, but pedestrians would run into it and get mad at me. I even took my bike on the subway when it was nearly deserted, late at night. MTA used to allow it, not sure if they do any more.
People yell at each other and you just kind of look at them and keep going, or you say something back, depending on the situation... nobody really takes it all that personally, at least they didn't back then... is it really any different now? Dunno...
