What is Audi A8's all-wheel steering system?

I've heard that the Audi A8 has an all-wheel steering system. How does it work and what are the benefits of having it?

The all-wheel steering system on the Audi A8 allows the rear wheels to turn in the same direction as the front wheels at high speeds, improving stability and handling. It also allows the rear wheels to turn in the opposite direction at lower speeds, making it easier to maneuver in tight spaces.

Having all-wheel steering on the Audi A8 gives you the best of both worlds - a stable and comfortable ride at high speeds and increased maneuverability at lower speeds. It's a great feature to have, especially if you live in a city with tight parking spaces.
