I guess if I lived in NY or London I might get rid of the car. But to be honest that's never entered my head here. I need the car to get to work. And yeah, there's parking there. But if there was no parking there, I'd still need car for everything else.
I get the point, there are cities where you can work,play, shop, school, all on public transport. Where ironically the streets are full of cars all the time. But alas, I don't live in one of those cities.
