Does Cruise Control Save Gas?

courtesy of Bob, The Auto Answer Man

My husband & I have differing opinions about using cruise control. I'm of the thinking (I don't know where I picked this up) that the cruise control will only save on fuel if you are driving straight and flat road with minimal braking. We live in the mountains. Up & down and around curves - doesn't that cause more fuel consumption with cruise control? Aren't there times when cruise control is not cost effective to use?

One common misconception about cruise control is that it was designed to save fuel. This is NOT the case. It was designed as a driver comfort. Depending on the vehicle, the driver might be able to maintain the speed better than the computer can. I can recall a mid 80 GM product. The cruise on this thing was the worst. It would oscilate by about 5 miles per hour and I could keep it dead steady with my foot.
Good Luck!
