How does the Audi A4's adaptive cruise control function in stop-and-go traffic?

I'm curious about the usage and effectiveness of the adaptive cruise control in the Audi A4, specifically when driving in stop-and-go traffic. How does it work and what should I expect in terms of performance?

The adaptive cruise control in the Audi A4 uses radar sensors to maintain a safe following distance from the vehicle in front of you, even in stop-and-go traffic. When the traffic comes to a complete stop, the car will also come to a complete stop and resume driving once the flow of traffic continues.
