I don't really understand why everyone in this post is so hung up on this. As long as there is no regulation in a particular area, obviously each actor will look out for their own interest. I wouldn't even call it selfish, it's just the natural order of things and an example of the tragedy of the commons. Nothing more, nothing less. The fact that people here act as if learning how to drive better and getting an SUV is an either/or choice is ridiculous.
