Just keep noticing that despite high gas prices people continue to speed. Coming out of downtown today in a 55 mph zone people were passing me doing 75 mph. Anybody that remembers their physics knows that this is eating up gas. I did some surfing around to get some more precise data. So on average you can think of every 10 mph you are losing approximately 4 mpg in efficiency.
So speed on as long as you are not one of those complainers about gas prices.
