How does adaptive cruise control work in the Audi A5?

I'm wondering about the specific mechanism behind the adaptive cruise control feature in the Audi A5. Can you explain it in technical terms?

Adaptive cruise control in the Audi A5 uses a combination of sensors, lasers, and cameras to detect and monitor the speed and distance of vehicles in front of you. It then adjusts your car's speed to maintain a safe following distance.

The adaptive cruise control feature in the Audi A5 also has Stop&Go functionality, meaning it can bring the car to a complete stop and resume automatically in heavy traffic. This adds convenience and safety in bumper-to-bumper situations.

One thing to keep in mind with adaptive cruise control is that it is not a substitute for paying attention to the road and other drivers. Always be prepared to take control of the vehicle if needed.
