How does Audi's adaptive cruise control work in the A8?

I'm considering buying an Audi A8 and I'm interested in learning more about how their adaptive cruise control system works. Can you explain the technology behind it and how it differs from traditional cruise control?

Audi's adaptive cruise control uses radar and camera technology to monitor the speed and distance of the vehicle in front of you. It automatically adjusts your speed to maintain a safe following distance and can even bring the car to a complete stop if needed. It's a step above traditional cruise control which only maintains a set speed.

Not only does the Audi A8's adaptive cruise control keep you at a safe distance from the car in front of you, it also has the ability to recognize and respond to speed limit signs. The car automatically adjusts its speed to match the posted limit, making it a great feature for long road trips.
