I live in a family of 6, and we were able to live car free for a year when we lived in germany. My dad used to live and work 300 kilometers away, and he would visit us every few weeks, coming by high speed train. My mother did all the buying groceries by bike. And we didnt live in any big city. It was a town of less than 10.000 people. It is possible for families to live car free. We did roadtrips by bike, visited nearby cities, went to beaches by train. We did have the car of a relative available, but we used it some 5 or 6 times in the whole year.
I dont care if you have a family, you can live car free, if in the right place. And we aren’t super rich or anything, we lived with our relatives, and my dad lived in a friend’s house, who gave him a very big discount.
And we also didn’t have any 3 bikes each, our bikes were mostly oldies borrowed from old family friends who didn’t need them.
And if you do the math, 100 dolars a month, is pretty cheap for a car, if you consider gas and wear, so it is cheaper to buy a pretty nice bike every 3 months than to own a car.
