I could put your Honda Civic LX in the back of my Chevy Silverado 2000 extended cab pickup, but as long as I keep driving this vehicle I don't encourage the automakers to waste resources by mining and drilling and building more. If I bought a more energy efficient vehicle I'd be paying for less gas but also making monthly car payments (no wad of cash to pay it off all at once). It wouldn't save me anything.

That's my story and I'm sticking to it. I also have under 100,000 miles still.
