I'm 38 and have never even had a drivers license. I grew up near Oslo, Norway, and moved to London when I was 25 - it's always been so easy to just use public transport that I've never gotten around to it. Keep thinking about it, as it'd be nice to have a license for the occasional car trip for vacations etc., but it's pretty far down the list of "nice to have"'s. Can spend a lot on taxis for what a car would cost me.
