I wish I could remember where I've read the statistics, but the majority of air pollutants don't come from cars, they come from the industrial complex, including power plants. What the article is saying is that the amount of CO2 placed into the air by coal fired electrical plants is orders of magnitude higher than that of a gasoline engine. The article mentioned didn't state where a lot of our coal comes from - China and Russia.

I don't disagree with either of you one bit on that. I'm a big fan of advancing technology, especially in the area of fossil fuel independence. I'm seriously considering trading in the pick-em-up truck for a Ford Escape Hybrid gas/electric SUV when they are released later this year. It's the subterfuge - replacing Arab oil with Chinese coal - that I wanted to point out in the article, I wasn't trying to downplay the impact of more efficient vehicles.

I'd love to see this work, seriously. I think within 3 more years we'll see some serious advances in vehicle efficiency. Hell, even Saturn is working on a gas/electric hybrid to come out within the next 3 years, and they're about as slow as molasses when it comes to keeping up with the times.
