Agree that a significant increase in fuel $$$ will have an effect. At least for awhile. Public service announcements would have a great effect too, as they did with tobacco use, drinking/driving, seat belt laws, etc. These issues were hammered into our heads repeatedly on TV, radio, and billboards.

But how often have you seen anything talking about driving techniques and fuel savings? How many people realize the dramatic fuel consumption penalty required to accelerate a dead weight vehicle to speed under heavy throttle? Or how efficient it is to coast to the red light ahead, instead of barreling down full speed, then slamming on the brakes.

Makes me wonder now how politically important the 'energy crisis' around the world is. Obviously record oil company profits doesn't upset congress as much as baseball player's reported steroid use. Go figure.
