Try hypermiling around Chicago....you'll get great mileage as the semi's push you down the road....coast to a light? RIGHT!!! And downhill costing in a hybrid is cheating, it's generating electricity into the batteries! The 81mpg is not a real world "practical" number. That's why they estimated 57mpg, they figured they would be driving like semi-normal people. You can be sure they were using tactics during the dead of night that would never hold up during daytime traffic.
