What is the Lane Departure Warning feature on the Audi A1?

I've heard that the Audi A1 has a Lane Departure Warning feature but I'm not sure what it does or how it works. Can someone explain it to me?

The Lane Departure Warning feature is a safety system that uses cameras to monitor the lane markings on the road. If the system detects that the car is drifting out of its lane without the turn signal being activated, it will alert the driver with a visual and audible warning. It's a great feature for preventing accidents caused by driver inattention or drowsiness.

Essentially, the Lane Departure Warning feature acts as an extra set of eyes on the road. It can detect when the car is unintentionally leaving its lane and sends a warning to the driver, helping to prevent potential collisions. It's especially helpful on long trips or in heavy traffic.
