Cruise controlCruise control is a system to control the speed of an automobile. The driver sets the speed and the system will take over the acceleration of the car to maintain the same speed. Most systems can be turned off explicitly, or automatically when the driver hits the brake. Cruise control often includes a resume feature to resume the set speed after braking and a coast feature to reset the speed lower without braking.
This feature can be handy for long drives across sparsely populated roads, and usually results in higher gas mileage.
