How does the Adaptive Cruise Control (ACC) system work in the Audi A7?

I'm considering purchasing an Audi A7 and I'm curious about the ACC system. Can you explain how this feature works and if it's worth the extra cost?

The ACC system in the Audi A7 uses radar sensors to maintain a safe distance from the car ahead of you. This feature is useful for long highway drives and can reduce the risk of rear-end collisions. My personal advice would be to opt for this feature if you do a lot of highway driving and want an extra layer of safety.

ACC in the Audi A7 also includes stop-and-go functionality, meaning it can bring the car to a complete stop and resume driving in low-speed traffic. This can alleviate some of the stress of heavy traffic situations. In my experience, it's definitely worth the additional cost for this feature.

In addition to maintaining a safe distance, the ACC system also has the ability to adjust your speed based on speed limit signs and curves in the road. It can even detect and respond to traffic signals in some areas. Overall, this feature adds a level of convenience and safety to your daily commute.
