Cruise control is a feature in vehicles that automatically controls the speed of the car. Once activated, it allows the driver to maintain a steady speed without having to keep their foot on the accelerator pedal. This can be particularly useful during long drives on highways, helping to reduce fatigue and improve fuel efficiency. Modern vehicles often come with advanced versions of cruise control, such as adaptive cruise control. This system can adjust the car's speed based on the distance to the vehicle ahead, automatically slowing down or speeding up as needed. This enhances safety and convenience for drivers.
