How does the new Audi A8's lane departure warning system work?

I've heard that the Audi A8 has a lane departure warning system, but I'm not sure how it actually works. Can you explain it to me in detail?

The lane departure warning system in the Audi A8 uses a combination of cameras and sensors to monitor the lane markings on the road. If the car begins to drift out of its lane without the turn signal on, the system will alert the driver with visual and audio warnings.

The Audi A8's lane departure warning system also has a corrective function, where it can gently steer the car back into its lane if necessary. This can be especially helpful in preventing accidents on highways or long stretches of road.

In addition to lane departure warning, the Audi A8 also has a blind spot monitoring system that can detect vehicles in your blind spot and warn you if you attempt to change lanes. It's an added safety feature that makes driving even more stress-free.
