Speaking of cars . . . You know that set of buttons around your steering wheel you almost never use? Well, you’ve already bought them, so it's time to make them earn their cost. By using cruise control when possible, you can save an average of 7% and potentially up to 14% of the fuel during a trip.
Apparently, cruise control not only eliminates the frequent speeding up and slowing down we do when our foot's on the pedal, but we're less inclined to weave and make unnecessary moves when in cruise mode (guilty as charged!); however, this benefit is only on flat roads and not in mountainous ones where the mechanisms will overwork trying to maintain your set speed.
So the car is driving itself and saving you money -- sounds like a good deal to me.
