I would bike commute in a second if I worked somewhere that wasn't in a very nonsafe-for-bikers area of Manhattan and where I could go to work in clothing that's possible to bike in.

...And if they DID start penalizing drivers, the first might change.

I agree. I think emergency vehicles, delivery vehicles, and other people whose careers require cars should be allowed to get a permit, and anyone else who wants to bring a car into Manhattan should have to pay a daily fee for the privilege.
