@omad: i'm not really familiar with the in and out of transportation costs in NYC since i myself don't live near the city. but i know for sure that driving around NYC is not only expensive, but very stressful as well. i'd say it's based on experience coz i have to drive within the city whenever we go visit some family friends down in Queens and i drove down 42nd street with my car and it stressed me out like hell. i swear to God i would never do that again. for me, the last thing i would wanna do while i'm alive is to be a taxi driver in NYC.
i'd rather drive around DC than in NYC that's for sure. anyway, i guess it's a smart move to get EZ pass when you decide to bring your car around the city.
oh, forget about parking your car... that's another story. you'd get lucky if you find a spot, unless you're ready to pay huge amounts.
