Yes, more is better here for the time being. However there is a real danger. In technical jargon it is called the "Rebound effect". When your car or SUV gets better miles per gallon, the average cost of driving per mile goes down. This makes it more attractive to drive, so people drive more. It is estimated that this rebound effect is of the order of 20%. This is not insignificant. Hence, Drive Lite!
