Cruise Control is an automotive technology that self-regulates a vehicle's speed without driver intervention. In the case of a Mini Cooper, this means that a driver can select a desired speed, and the car will automatically maintain it, even on inclines or declines.
Cruise control is a valuable feature for long road trips, as it can reduce driver fatigue. It can also be helpful in traffic, as it can prevent the driver from speeding up or slowing down too quickly. The technology was first developed in the 1950s, and has since become a standard feature on most modern cars.
