What is the Lane Departure Warning System in Audi A7?

I recently purchased an Audi A7 and noticed a feature called Lane Departure Warning System. Can someone explain what this feature does and how it works?

The Lane Departure Warning System is a safety feature that helps drivers by alerting them when they unintentionally drift out of their lane. If you start to cross lane boundaries without using your turn signal, the system will send a visual and audible alert. This can help prevent accidents caused by distracted driving or drowsiness.

This feature uses a camera and advanced software to detect lane markings on the road. It then compares your vehicle's position to those markings and can determine if you are drifting out of your lane. It's a helpful tool for staying alert and staying safe on the road.

I've found that the Lane Departure Warning System is especially useful on long highway drives. It can be easy to lose focus and drift out of your lane, but this feature helps keep you in check. Just make sure to still pay attention to the road and not rely solely on the system.
