What is the Active Lane Preservation System in Audi A8 and how does it work?

I was looking through the safety features of the Audi A8 and came across this system. Can someone explain how it works and its benefits?

The Active Lane Preservation System in the Audi A8 is a safety feature that helps to prevent unintentional lane departures. It uses a camera system to monitor the lanes and will gently steer the car back into its designated lane if it detects drifting. It can also provide haptic feedback through the steering wheel to alert the driver of lane departure.

I've been using the Active Lane Preservation System in my A8 for a while now and it has definitely helped me stay more alert and focused on the road. It's especially useful on longer highway drives when I may be more prone to drifting.
