based off something that they can't prove...The new CAFE standards, ethanol being added to gasoline, etc. Everyone running around like the end of the world is coming, it's all hype. If you think man's activity is the problem then you personally stop driving you Z...just don't force me by supporting all these new gov't mandates to no longer drive my Z and not have the ability to buy a performance car in the future (that has any power). I love nature, live on 5 acres and I think we should take care of it. But we also should enjoy it. This whole issue is politically motivated and I'm just tired of everyone assuming this whole thing is the gospel when there is no possible way to scientifically prove this one way or the other...it's all theory and that has changed like crazy
