Several states, as well as our federal government, believe that it is important to mandate increase fuel efficiency standards and reduce the level of carbon dioxide coming out of automobile tailpipes.  But are such policies wise?  Not according to Sam Kazman of the Competitive Enterprise Institute, who has this to say: “Fuel efficiency mandates and carbon dioxide emissions limits are political correct, but they are also dangerous.  They make cars less crash-worthy by reducing their weight, and so they increase highway deaths by the thousands.  Their proponents claim that these lethal effects are a thing of the past as technology has improved, but the facts are they kill – and that is something these people just  won’t admit.”
