Lol Scott, no way. First, I really doubt the amish play PS3 or post on internet boards. Then, once you're burnt by one cult you're probably careful next time joining an other cult.
Why, do you think a car is really necessary for today's living in all cases? I can get anywhere walking in a matter of minutes; starting up a car, and waiting at traffic lights would probably take longer. When going shopping to a mall, the taxi will take me home for about 3-4 USD. So why should I bother?
It's a different story in a metropolitan area of course, I'm not saying cars are bad, I just didn't feel the need for them.
