No chance of anything so logical and righteous here in the States. Politicians from ethanol states, oil states, and (auto) labor union states have vested interests. Stir in Federal and State treasuries who simply adore gas and diesel taxes, and tax shortfalls that efficiency would bring, and one has a truly unholy alliance against efficiency.
US politicians will NEVER allow higher fuel economy standards to be imposed.
Ah! A voice of logic in the vastness of "Sheeple"! And...did you vote in our last popularity conte$t? "Sludgy", your mind is as clear as can be! Kudos!
