I've thought about this too. MPG as a standalone piece of data does not. MPG as you're driving does. 55 MPG at 20 MPH is a lot different than 55 MPG at 60 MPH. They're different GPH burn rates.

When you ask for a tray to carry the steaks out to the BBQ grill, and your wife hands you a pizza pan and says, "Here, use this hubcap."

I actually caught myself doing this in the grocery store last night, my fiance was wondering what the hell I was doing.

I was pushing the cart (awww yeah!) and when I would get to a fairly brisk pace, I would let go of the cart and let it coast, call it pulse and glide if you will. By letting go of the cart and allowing it's stored energy be spent, I saved myself energy by not having to push a load. I estimate my CPR (calories per hour) was at least 50% above the EPA. THEN, on the way to the parking lot, there is a ramp that goes down to the street, guess what? YEAH coasted that mug. But don't worry, I looked far ahead before deciding what my action would be, just like a good hypermiler should do. In my head this sounded awesome, now after reading what I typed.... damn I'm a nerd.

In other oddball associations to hypermiling, I do some jogging with a heart rate monitor. On hills, you have to give up speed to keep beats per minute down, exactly as you have to dump speed to keep mpg the same in a car. The same holds true downhill, but sadly I don't coast as well downhill as my 2.5 ton car does

Heh. I used to P&G on our high school cross country course. Racing doesn't reward you for time, just position. A large part of our course was through the woods- sometimes through clearings and sometimes on narrow trails.

I'd dog it on the trails and put on speed right before the clearings. Just a couple steps of lead and I could hold it no problem until I hit the next narrow trail section, where I'd relax and they'd come zipping up to get stuck in the no passing zone. The other runners were hilarious, because they didn't understand that there's a difference between running and racing.

I'm not always happy how my <1 ton car can coast too well on many declines. Sometimes it can be more convenient than my 180km motorcycle, but it also means that more roads are too steep and I'm forced to throw away more precious momentum

Sometimes I can mend it by DWLing up where I pulse with Teresa - but sometimes it doesn't help.
