I didn't get a driver's license until my first child was born and I lived in the middle of nowhere. I was car light until then, as I depended on DH to drive me when a car trip was necessary.

For a while, we lived in different cities and I was truely car free. The bike, walking or the bus were pretty much my options. (I was thinner, then. . .) The older neighborhood we lived in was pretty walkable/bikeable, so I didn't feel a great need for a car.

Now, I'm back to car light. There are three drivers, including my social butterfly daughter, who share one car. There is much negotiation, and I'm on the bike as often as not when I need to go somewhere.

So, in answer to the original question, I've only been car free one year in my life. It's kinda pitiful, when put like that.
