What is the functionality of the Audi A7 Lane Departure Warning system?

I just got my new Audi A7 and was wondering what the Lane Departure Warning system does and how it helps improve safety while driving. Can you provide some insights on its features and how it works?

The Audi A7 Lane Departure Warning system is designed to prevent unintended lane departures by monitoring the vehicle's position on the road. It uses a camera to detect lane markings and alerts the driver if the car is drifting out of its lane without using a turn signal.
