How does the Audi A8's adaptive cruise control work in stop-and-go traffic?

I'm curious about how the adaptive cruise control system in the Audi A8 handles stop-and-go traffic situations. Does it smoothly slow down and speed up, or does it have sudden, jarring movements?

The adaptive cruise control system in the Audi A8 uses radar sensors to detect and maintain a safe following distance from the car in front of you. It can smoothly slow down and speed up in stop-and-go traffic, making for a comfortable driving experience.
