What is Audi A7's adaptive cruise control and how does it work?

I'm considering purchasing an Audi A7 and am intrigued by its adaptive cruise control feature. Can someone explain how this feature works and how it differs from traditional cruise control?

Audi A7's adaptive cruise control system uses sensors to detect the distance between your car and the car in front of you. It then automatically adjusts your speed to maintain a safe following distance. This feature also includes stop-and-go capability, allowing the car to accelerate and brake in heavy traffic. My advice is to familiarize yourself with the controls and settings before using this feature on the road.
