How does the Audi A5 adaptive cruise control work?

I'm interested in purchasing an Audi A5 and have heard about their adaptive cruise control system. Can you provide more information about how it actually works and if it's worth the added cost?

The Audi A5 adaptive cruise control uses sensors to detect the distance of vehicles in front and adjusts the speed accordingly. It also has the ability to bring the car to a complete stop and resume following when traffic starts moving again.

From my experience, the adaptive cruise control in the A5 is a game changer. Not only does it make long drives more comfortable and less tiring, but it also adds an extra layer of safety by maintaining a safe distance from other vehicles.

I've found that the adaptive cruise control works seamlessly with the automatic braking and lane keeping features in the A5. It makes for a smooth and stress-free driving experience, especially in heavy traffic.
