When you get a new person in your area, the VERY FIRST THING to do with them, is try to find a way to save them money with car sharing and/or car pooling, and at the same time, appeal to a visceral anger at the massive profits of the oil companies, while they pay through the nose for gasoline.

There's anger at high gas prices; USE THAT ANGER to push car pooling and car sharing. Describe pictures of them car pooling, and oil company executives tearing their hair out.

Explain to people that their infrastructure is designed for massive oil use, and that the worst fear of oil company executives is a fundamental culture change (hat tip to Jan Lundberg) away from the private automobile, which averages only 5 mph nationwide anyway.

Sure, there is some inconvenience in having to share a car. Ask people to do the math of what they spend on their car, and see if sharing might be worth the money saved.

Americans have lost the habit of trusting one another and sharing. Challenge people to try it again. Make sure you get a lawyer to write a car sharing contract -- contact me if you need one, my wife is a lawyer. Some tight knit religious communities do car sharing, and they always have a new car that they trade in every two years. So you aren't dealing with unexpected breakdowns, and if there is a breakdown, it's under warranty. With car sharing, there should be ZERO unexpected expenses. You are warrantied and insured to the hilt.

If you have 4 or 5 people in your area, give this a try. I don't have enough people locally yet to do this, but you can be sure I will when I do.
