I live in Germany, and I neither have a driver's license, nor do I own a car. Same for many of my friends and colleagues.
In cities, almost everything is faster by bike than by car. European cities are very dense, parking space is scarce and many inner cities are car-free.
Public transport infrastructure is great and while people like to complain about Deutsche Bahn (the railway company), it's still more predictable and comfortable than driving a car.
Oh, and did I mention how much money it saves not to own a car?
