I hate hummers and think that the folks who drive them are making up for their's or their husbands' small Gherkins but lets get real-- if there are 6 people in there that's more people miles per gallon than a crx with one. A bus with less than 9 people? Better for the environment if they all drove reasonable cars. And lastly I've heard that 2 tablespoon of spilled raw fuel (ATV. lawnmover, weedwacker,etc) is as harmful to the environment as a gallon or more of burned fuel.
