Yep gas going down, oil going down ..... I guess there's the heating oil season coming up now, and I'm willing to bet demand destruction will be evident there too, lots of people haven't insulated their houses as well as they could, wore t-shirts inside last winter, etc.
Even if gas were free, cars are evil. A visitor from another planet could easily think cars are the dominent life form on Earth if they landed anywhere in the "first world" and in many places in the "third world" too. Stinking, polluting, dangerous, noisy, awful things.
