Most cruise controls will disengage if the gas pedal has to go too far or if the speed drops too much.
going down hill, cruise control, a strong wind, getting rear ended by someone whos going twice as fast.
When you use cruise control it does all it can to keep you going at the speed you set it at. That means if you are going up a steep hill it will hit the gas to try to maintain your speed. When going up hills if you slow down just a few miles an hour you can save more fuel. Hard acceleration greatly reduces your fuel mileage. Many cruise controls will accelerate very hard when your car slows down.
