I lived in a European capital until 28 and never got a driver's license because public transport was faster than driving through horrible traffic.

Moved to the US and in less than a year had to buy a car because it was impossible to do anything without one. And that was in am area with considerably better public transport than usual for the US. It was just my wife driving, but after a few years I had to get a driver's license too and buy a second car. I like walking, I prefer good public transit to driving, but it's simply not an option in most of the US.

Oh, and another story. In my hometown I absolutely loved the subway as THE way to get around. It was cool in the summer, warm in the winter, and average wait was 2-3 minutes. I visited New York one summer and as per habit I went to take the subway to my destination. It was sweltering hot and I waited 20 minutes for a train. Up to that point I considered NYC to be the closest US city to what I'm used to, but that would have been a deal breaker.
