How does the Audi A8's all-wheel steering feature improve handling?

I'm interested in purchasing an Audi A8 and have read about its all-wheel steering feature. Can someone explain how it works and how it affects the car's handling?

The Audi A8's all-wheel steering allows the rear wheels to turn in the opposite direction of the front wheels at low speeds, making it easier to maneuver in tight spaces. At higher speeds, the rear wheels turn in the same direction as the front wheels, providing improved stability and cornering abilities.

I have an Audi A8 and the all-wheel steering has significantly improved my driving experience. It allows for smoother and more precise turns, making it easier to navigate through curves and tight turns.
