Yeah that's pretty much how it goes. We're as hung up about cars as the ancient Norse Greenlanders were about having cows (which could barely survive there, and what's more the Norse Greenlanders refused to eat fish! They died out.) It's financially insane to spend all this money on a car, but you're an outcast if you don't.
You're right, maybe when pollution is clearly killing the ecosystem and gas is $10 a gallon......
