How do lane departure warning systems work in the Audi A3?

I'm curious about the lane departure warning feature in the Audi A3. Can anyone explain how it works and how accurate it is?

Lane departure warning systems utilize cameras and sensors to monitor the lanes on the road. When the vehicle starts to drift out of its lane, the system will send a warning signal to alert the driver. In the Audi A3, the system is very accurate and can even detect when the car is about to cross over the line.

I've found the lane departure warning in the Audi A3 to be very helpful, especially on long highway drives. It works by tracking the painted lines on the road and can even detect if the driver is intentionally changing lanes.

I've had a few close calls with the lane departure warning system in the Audi A3. It's not always accurate and can sometimes give false alarms. I recommend not relying solely on this feature and always staying alert while driving.
