Yup!
Yesterday, I was in back of a guy with a fairly late-model Accord, and he was braking his car every few seconds as a result of his tailgating. Because I kept a safe following distance, I rarely had to do any braking.
What I found to be interesting was that the only brake light on his car that still worked was the left rear, so in addition to wearing-out his brakes prematurely and ruining his gas mileage, he is clearly also burning out brake light bulbs prematurely. Once he burns-out that one remaining brake light, he will probably get rear-ended, and I feel sorry for the poor schmuck who does actually rear-end him.

I’m gonna get my dash cam from that dusty closet now 
Good ideas all around. About the best the owner can do as far as the engine is concerned is keep the suggested maintenance up to date, a make sure it is running at the correct operating temperature. If the coolant is even a little lower in temperature than it should due to a warped, leaky, or stuck thermostat, that can significantly degrade mpg. There’s no check engine light on, right?
Sounds like you drive just like I do and my wife drives just like yours with similar results. I try to think of the brake pedal as a device that turns gasoline into heat instead of propelling the car.
The above was supposed to be a reply to MikeinNH and I can’ seem to edit who it is too.
