What is the difference between adaptive cruise control and active lane assist?

I recently purchased an Audi A8 and noticed that it has both adaptive cruise control and active lane assist. Can anyone explain the differences between these two features and how they work together to enhance the driving experience?

Adaptive cruise control is designed to maintain a safe distance between your vehicle and the car in front of you by automatically adjusting your speed. Active lane assist, on the other hand, uses cameras to monitor lane markings and helps keep your car centered in its lane.

I've found that using both adaptive cruise control and active lane assist together can make for a more relaxed and less fatiguing driving experience, especially on long trips. Just remember to always stay alert and ready to take control if needed.
