For most people, it's not really binary. For instance, when I lived in Italy, we did have one car for our family of four. We used it to go see the in-laws and stay late at dinner when there were no public transit options to get home. But we took the tram downtown with our small kids. And I rode my bike to work often. And my wife and I would go out on dates riding our bikes. And I'd walk our kids to school. And if we wanted to go hiking out in the hills, we'd drive. So it wasn't so much about a zero-car lifestyle as a 'right tool for the job'.
