What are the advantages of the Audi A8's all-wheel steering technology?

I'm considering purchasing an Audi A8, and I've heard that it comes with all-wheel steering technology. Can someone explain what this technology does and how it benefits the driving experience?

All-wheel steering technology allows for better maneuverability and handling, by allowing the rear wheels to turn in the same direction as the front wheels at low speeds, and in the opposite direction at high speeds.

The Audi A8's all-wheel steering technology also reduces the turning radius, making it easier to navigate tight corners and parking spaces.

Not only does the all-wheel steering technology improve handling, but it also enhances stability at higher speeds and increases overall vehicle control.
