How Does Lane Departure Warning Work in the Audi A2?

I'm interested in purchasing an Audi A2 but I'm not familiar with the Lane Departure Warning feature. Can someone explain how it works and how effective it is in preventing accidents?

The Lane Departure Warning feature in the Audi A2 uses a camera to detect lane markings and monitors your vehicle's position within the lane. If your vehicle starts to drift out of its lane without a turn signal, the system will alert you with visual and audible notifications.

In my experience, the Lane Departure Warning feature has been very effective in preventing accidents. It's particularly helpful for long drives or when you're feeling fatigued and may not be paying as close attention to your lane position.
