On Seinfeld, Jerry, Kramer, and George all had cars. That's something I never understood. Why? If you live in Queens or Brooklyn, that's understandable. But why have a car in Manhattan? It's more a pain in the ass then anything. I say that as someone who freaks out at all the cars causing the traffic while in a cab, desperately trying to get somewhere. The Times tries to delve deeper in the minds of the crazy Manhattanites who do have cars. One is New Yorker humorist Bruce McCall. Gothamist speculates that one thing New Yorkers are jealous (relative to non-New Yorkers) is just being able to drive...not that rush hour traffic on 78 is fun, but there is that liberating feeling of being out on the road, miles of highway and not a care in the world.
