I remember just enough high school physics to know that if you don't press the brakes, you can't take advantage of regenerative braking.
My folks live about 800 miles away. If I didn't have to eat or take a leak for about 13 1/2 hours, I could drive there in my 2000 Acura 3.2 TL stopping for gas only once.
The term "braking" is a technical term. Any vehicle in motion is constantly "braking". Read the article I noted above, and you will get a better understanding than I can give you. I'm just a salesman...
