I really don't care about the mankind that much any more. As species, we are doomed by greed, hatred and stupidity anyway. Not much I can do here.
Some of my main reasons were in the poll: it's faster and I do this for health reasons. But not only it's faster, it's more reliable and predictable. Mass transit can take 50 minutes or 2 hours. My bike commute is pretty much the same most of the time, gets 5- 10 minutes longer in bad weather, maybe 15 mins in Winter, but it's predictable: I know up to 5 minutes when I will be at work. I get a flat maybe once a year. With mass transit in NYC it's a gamble.
Yes, I do enjoy being different from the street crowds, I don't want to be another caffeinated zombie and it makes my day when people think I'm crazy. Except, today I was the only person in the office that had dry clothes on

I also dislike the NYC subways in general. I don't like be squeezed in crowds, I don't like to wait for delayed trains, I don't like to get stuck on crowded trains. I'd rather be wet and sweaty on a bike.
But, I think, above all
I really like to ride (yeah, that should be added as an option to the poll!) and
I like the feeling of freedom and being in control that it comes with riding a bike. I'm no longer on the mercy of the MTA (NYC Transit), I'm not encaged in a metal box underground that I don't have control over. I can stop when and where I want, I can detour at will, I can get off an walk, no traffic or congestion can prevent me from moving. I can run errands in Manhattan in fraction of the time.
Bicycle is the most nimble, independent and reliable method of transportation.
