It was interesting to see how many people were not really “filling up” but rather putting a certain amount of gasoline into their tanks.  Now we can watch as a nation now long we stay “conscious” and what solutions we start to draw.  The answers are probably much easier than we think.  Making every vehicle weigh less would improve mileage.  Looking at alternative lighter weight metals that are actually stronger might be just what the doctor – or nation – ordered.  Biofuels, natural gas, hybrids, electrics – all good steps, but I have to wonder if we are making this problem more complicated than it needs to be.
