How does the adaptive cruise control system on an Audi A7 work?

I've heard about the adaptive cruise control on the Audi A7, but I'm not entirely sure how it functions. Could you explain how this feature works and whether or not it's worth getting?

The adaptive cruise control on the Audi A7 uses radar and camera sensors to track the distance of the vehicle in front of you. It automatically adjusts your speed to maintain a safe following distance, making highway driving more convenient and less stressful.

I highly recommend getting the adaptive cruise control as it's a great safety feature. It not only maintains a safe distance, but it can also bring your vehicle to a complete stop in heavy traffic and resume following once the traffic moves again.

The adaptive cruise control system on the Audi A7 also has the capability to match the speed and braking of the vehicle ahead of you, making it even easier to navigate through stop-and-go traffic.
