How does lane departure warning system work in the Audi A8?

I was reading about the Audi A8 and noticed it has a lane departure warning system. Can someone explain how it works and if it's worth getting?

The Audi A8 uses a combination of cameras and sensors to detect lane markings and monitor the vehicle's position in the lane. If the vehicle starts to drift out of the lane without the use of a turn signal, the system will provide visual and audible warnings to alert the driver. It's definitely worth getting as it adds an extra layer of safety to your driving experience.

Once the lane departure warning system is activated, it will constantly monitor and analyze the vehicle's surroundings. In case of any lane drift, the system will alert the driver to take corrective action. I highly recommend getting this feature as it can prevent accidents and promote better driving habits.
