What does the Audi A6's Dynamic all-wheel steering system do?

I've heard that the Audi A6 has a Dynamic all-wheel steering system. Can someone explain what this feature does and how it benefits the driving experience?

The Dynamic all-wheel steering system in the Audi A6 improves the car's handling and stability by adjusting the steering angle of the rear wheels based on the car's speed and direction. It adds precision and agility to the driving experience, making maneuvers smoother and more efficient.

As someone who drives an Audi A6 with the Dynamic all-wheel steering, I can tell you that it makes a noticeable difference in tight turns and parking. The rear wheels turn in the opposite direction of the front wheels at lower speeds, making the car easier to maneuver and reducing the turning circle. At higher speeds, they turn in the same direction as the front wheels, adding stability and improving cornering.
