How does the Audi A7's all-wheel steering system improve handling?

I've heard that the Audi A7 has an available all-wheel steering system, but I'm not sure how it affects the driving experience. Can someone please explain how this feature works and what benefits it provides?

The Audi A7's all-wheel steering system allows for the rear wheels to turn in the opposite direction of the front wheels at low speeds, providing better maneuverability and a tighter turning radius. This improves handling and makes navigating tight spaces and parking easier.

At higher speeds, the rear wheels turn in the same direction as the front wheels, increasing stability and making lane changes and highway driving smoother and more controlled.
