I'm car-light... Well, I don't own a car myself and not riding one neither.
But my wife does have a company car that she's an addict, using it for the weekly shopping and other daily stuff.
So therefore, I'm not car free....
However, I'm 30 and never owned one myself, I go by foot, bike or trains. In the city: trams or metro,... don't like the bus that much.
I do have a drivers-licence. Did it to drive the car to replace my wife when she has a broken leg.
I used this drivers-knowledge to drive her to hospital, once she was pregnant... left the car on the parking and the other following days I went to the hospital by train and by foot
Anyway, I just dislike driving, takes too much of my energy and focus.
And I'm a little ecologic too. I grow my own vegetables in the garden.
