My fuel economy increases by between 20 and 25 percent when I drive at 55 as opposed to 65+ (that is on highways where the speed limit is 55 - most drivers are driving at 65+ despite the posted 55). Boy, the dirty looks I get as I drive the posted limit. I’m not in that much of a hurry, sorry. I have better things to spend my hard earned dollars on then making a few oil men rich (too bad more people don’t realize this).
If you're not in that much of a hurry, take a different road and stay out of the left lane there too. It is inconsiderate and selfish to detain drivers who have places to go, people to see and things to do.
