A myth moving around the blogosphere reports that a ‘scientific study’ has shown that GMC Hummers are actually better for the environment than hybrids like the Toyota Prius, because of the cost and pollution involved in manufacturing the battery. “Bunk”, states this analysis in Slate Magazine, which notes that the so-called study has lots of faulty assumptions, such as assuming the lifespan of the Prius is only 109,000 miles, while that of the Hummer is 379,000 miles.
