How does the Audi A7's adaptive cruise control work in stop-and-go traffic?

I'm considering purchasing an Audi A7 and I've heard about the adaptive cruise control feature. How does it handle stop-and-go traffic situations?

The adaptive cruise control in the Audi A7 uses radar sensors to monitor the distance to the car in front of you and adjust your speed accordingly. In heavy traffic, it can bring your car to a complete stop and resume driving once the traffic begins to flow again.

I've been using the adaptive cruise control in my Audi A7 for my daily commute and it works great in stop-and-go traffic. It takes a lot of stress off my feet and legs and allows me to relax during my drive.
