At my age I figure I have more dollars than I do days. I'm damned sure not going to drive 55 to save chickenfeed money.54mph is a neat experiment. 40 mpg is remarkable
But itās just not practical for most freeway, interstate driving. You try that in any metro area, you are putting yourself and others in danger. Most of us donāt leave 10-20 minutes early so that we can play with our experiment. Drivers need to go with the flow. Hell, thatās why minimum speeds are posted. You wanna try that out in the farmlands of OH or driving thru the sticks in WV⦠knock yourself out. One might Become a victim of road rage or worse, cause an accident. I hope you are in the slow lane! Maybe get some shoe polish and jot out āexperimentalā on your back window.
I often drive on a two lane to a nearby state park. Speed limit is 50. Most of the time I set my cruise at 52. I have 245 tires so that knocks mileage a bit. I average 33 mpg almost every time.
For those with larger tires, I run WAZE gps. It shows your gps speed and almost every speed trap, stalled vehicle, debris on the road and of course construction. At 70-75 speedo is off about 2 mph. Waze has become my go to road trip app.
