I just read about this system and found it good to set the rash drivers 
Cruise control is an invaluable feature on Ameri¬can ¬cars. Without cruise control, long road trips would be more tiring, for the driver at least, and those of us suffering from lead-foot syndrome would probably get a lot more speeding tickets.
Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart. With traffic continually increasing, basic cruise control is becoming less useful, but instead of becoming obsolete, cruise control systems are adapting to this new reality — soon, cars will be equipped with adaptive cruise control, which will allow your ¬car to follow the car in front of it while continually adjusting speed to maintain a safe distance.
The cruise control system actually has a lot of functions other than controlling the speed of your car. For instance, some of the cruise control can accelerate or decelerate the car by 1 mph with the tap of a button. Hit the button five times to go 5 mph faster. There are also several important safety features — the cruise control will disengage as soon as you hit the brake pedal, and it won’t engage at speeds less than 25 mph (40 kph).
