well I'm with you op. I know some people who tried to live like that, refusing to buy a car out of principle, even when they had kids they would drive them around in a trailer even in sub zero temps, ****ing rain and in dangerous situations. Fools nearly killed their kids on a narrow road just to prove a point.
Anyway they now have a car which they use as little as possible, but do still have to use at times.
We recently went from 2 to 1 car, I mostly ride if I can but not if it's ****ing it down or too far to ride or inconvenient to ride.
I reckon anyone who says you dont need a car probably lives in a city and doesn't have children. It's a fact of life that we need a car, its how our world is constructed and foolish to think otherwise.
