Cruise control is a feature on many modern vehicles that allows the driver to set a desired speed and have the car maintain that speed without having to constantly adjust the gas pedal. This can be helpful on long road trips or in stop-and-go traffic, as it can reduce driver fatigue and improve fuel economy.
Cruise control has been around for decades, but it has become increasingly sophisticated in recent years. Many newer cars now have adaptive cruise control, which can automatically adjust the car's speed to maintain a safe following distance from the vehicle in front.
