Judge Roy Bean; I agree with you on being negative on the GW crowd, but you are spouting BS on gas cars using 4x the fuel of a diesel.
  FYI smaller displacement gas cars have become very efficient  in the last several years.  After renting a VW Passat 1.8L gas engined car for a few weeks and experiencing the same (90% highway) mileage as I've experienced with diesels, I decided diesels cars were now history.
 But this VW cheating has turned me off VW for any car.
