In Europe there are few places where knowing how to drive is necessary unless you need it for work or have specific hobbies / needs. Most people still learn to drive quite young, but many don't. I'm 39 and have still not bothered getting a drivers license because I've never felt a need for a car.
I'm a Scandinavian in my mid 30s and haven't bothered getting a driver's license either. I could certainly afford a car, but it's just too much hassle.
