What does the dynamic all-wheel steering in the Audi A7 do?

I've heard that the Audi A7 has dynamic all-wheel steering, but I'm not sure what that means or what it does. Can someone explain it to me?

The dynamic all-wheel steering system in the Audi A7 allows for precise control and stability when steering. It can adjust the rear wheels up to 5 degrees in the opposite direction of the front wheels to improve agility and reduce understeer.

With dynamic all-wheel steering, the Audi A7 can also adjust the rear wheels in the same direction as the front wheels at higher speeds, providing enhanced stability and control. It's a great feature for high-performance driving.

In addition to improved handling and stability, the dynamic all-wheel steering in the Audi A7 also helps with parking and maneuvering at low speeds by reducing the turning circle. This makes it easier to navigate tight spots and complex parking situations.
