How does the Audi A8's active lane assist work to improve driving safety?

I'm interested in learning more about the features of the Audi A8's active lane assist. How does it function and what are the benefits for drivers?

The active lane assist in the Audi A8 uses a camera and sensors to detect when the vehicle starts to drift out of its lane. It then gently corrects the steering to keep the car in its designated lane.

Not only does the active lane assist in the Audi A8 help prevent accidents caused by drifting out of lanes, it also reduces driver fatigue by providing subtle steering assistance.

With advanced technology and responsive sensors, the Audi A8's active lane assist can even recognize and respond to upcoming curves and turns in the road.
