Sounds like an interesting study, but it's missing some key info to put this in perspective. Americans use over 360 million gallons of gasoline PER DAY. And thats the average from mid March to mid April when demand had already fallen due to higher prices.
In 2011, we used almost 134 billion gallons of gasoline. So wasting 938 million gallons a year is less than 1%. Also compare the costs. We waste $4 billion a year but we spend over $520 billion a year (at $4 per gallon).

But the new car is three times more powerful. If Honda had continued to build 1.5L 65hp engines, they'd be getting 120mpg by now.
