On second thought, I guess experience differs a lot based on location. Not having a drivers licence is pretty unimaginable for me where I live.
Your college friends are not going to give you rides forever. And your work options, living options, and vacation options are going to be quite limited. Obviously some people do it, but it's hard to imagine for a typical middle-class professional over the long term.
Even people I've known in Manhattan who put it off for a few years learned to drive eventually.
On the other hand, I know a lot of city dwellers and even those few who don't own cars because they don't need one day to day are constantly using either short-term or longer-term rentals to get around the surrounding area for various activities. (Or doing those activities with people who have cars though that tends to become more difficult as your circle of friends gets older.)
On another note if I had a daughter, I would be more careful. I don’t think anyone is going to bother my 6 foot 200 pound son.....
