Apparently, the problem is that we used to have the technology, but somebody lost the recipe.
Wake up, the technology is there and used somewhere else: Avg fuel consumption in Europe: 40mpg. All these diesels are very efficient (and are cleaner now). American manufacturers have been sleeping for a looong time.
It is all about promoting efficiency and taxing glutony (as they do in Europe since the 70's). Only the govt can do that. Be smart.
