Small savings above 35 mpg

Recently I wrote about how increasing mpg above about 35 mpg leads to diminishing returns.  Sam Abuelsamid over at AutoBlogGreen just published an article which shows how quickly the savings per year declines once you get above 35-40 mpg:

Imagine, if you will, taking a sheet of paper and cutting it in half. Now take one of those halves and cut it in half again. Now keep repeating the process. As you keep cutting, the difference in the size of the subsequent pieces gets progressively smaller. This simple example is a demonstration of why continuing to increase the fuel mileage of a vehicle has less and less impact once you get beyond about 35-40 mpg.

That doesn't diminish the fun of driving for maximum mpg though!
