What a fascinating and mind bendingly mathmatical concept. It sure makes me feel good for driving my V6 Ranger at 22% over EPA. One thing I felt that the people commenting on the original article overlooked is the fact that all these trucks and SUVs are already out here. Even if you get all of the owners to switch to compacts or hybrids, what are you gonna do with all the trucks? Landfill them? And what about the impact of manufacturing all those new cars? Grand visions of a hydrogen or electric future are great, but in the mean time we need to get the most out of what we have now! I was gonna get a motorcycle to reduce my footprint a bit, but now I think maybe a dump truck driven carefully may have a bigger impact.
