Better a full parking lot than an empty one.But you do have a point about being responsible. God gave us dominion over the Earth & we do have an obligation to use it's resources wisely.
We have our two family cars, the spare van we use mainly for trips, and my two kids each have a car (one's away at college). Everyone goes their own way each day, so I could not imagine not having that many. Then, when my son comes home from college, he invites his rock-band friends over, and there's another 3 cars in our driveway at least. I came home one day and found over 10 cars parked at my house! This is typical around here. Good thing my driveway's 300 feet long with plenty of yard space at the side for more and more cars.
