When I can park my car in my driveway at no marginal cost to myself, most people (including me) would call that free.

If you have a driveway. I had to look around hard for a house with a car port that wasn't just a slot in a crowded alley, heck, I saw some beautiful houses that had no effective parking at all (maybe they had sunk garages built in 1920 that were not usable by modern cars).
