How does the Adaptive Cruise Control feature work in the Audi A7?

I'm considering purchasing an Audi A7 and I'm curious about the Adaptive Cruise Control feature. How does it function and what are its limitations?

The Adaptive Cruise Control in the Audi A7 uses a radar system to maintain a set distance from the vehicle ahead of you. It can control speed, braking, and acceleration, making long drives easier and more comfortable.

While the Adaptive Cruise Control in the Audi A7 is very advanced, remember that it is not a substitute for attentive driving. Always be aware of your surroundings and ready to take control of the vehicle if necessary.

I've found that the Adaptive Cruise Control in the Audi A7 works best on straight highways with minimal traffic. In heavy traffic or on winding roads, it may struggle to maintain a set distance from other vehicles.
