I wonder why cars don't come up in this debate. A typical car space is 20 m². Usually the amount of parking spaces needed is greater than one (parking at several shopping locations, at work, ...). Parking often uses vertical space just once. So with a multi-storey house these 20 m² become enough for a flat housing a few people. And this still ignores public and non-public (like driveways) roads.
