What is Audi A3's ACC feature and how does it improve driving experience?

I recently purchased an Audi A3 and noticed it has an ACC feature. Can someone explain what this feature does and how it enhances the driving experience?

ACC stands for Adaptive Cruise Control, which is a driver assistance feature that uses sensors to automatically adjust your vehicle's speed and maintain a safe distance from the vehicle in front of you. This feature can make your long-distance drives more comfortable and safe by reducing the need for constant speed adjustments and giving you more time to react to changes in traffic.

In addition to maintaining a safe distance from other vehicles, ACC can also help reduce driver fatigue by automatically adjusting your speed to match the flow of traffic. This can be especially helpful in stop-and-go traffic situations where frequent manual adjustments can be tiring and distracting.
