I do get some awfully dirty looks...
When I have to drive my truck to work instead of my motorcycle, I set the cruise control @60 mph. My mileage went from about 375 miles per tank to over 500. The savings is significant, especially when it comes time to fill up that 25 gallon tank. But this is MY choice.
If there was a 55 mph law, I would probably crank it back up to 75, just on principle.
But I note that it's easy to spend other peoples' money (tens of thousands of dollars per family) on a war that "is required to secure the middle eastern oil flow, yet they are not willing to slow down to keep demand down.
Interesting phenomenon, sociologically. After all, the Iraq War costs could have paid for our foreign oil imports for 15 years...yet people complain about the costs of gasoline going up to $4/gallon. We bought an Iraq war instead of 5,000 gallons of gasoline for each American family, even at current pump prices...is this buyers' remorse coming on?
