How does the all-wheel steering system in the Audi A8 improve handling and maneuverability?

I recently came across the feature of all-wheel steering in the Audi A8 and I'm curious about its benefits and effects on driving performance. Can someone give me a breakdown of how this system works and how it enhances the overall handling and maneuverability of the car?

The all-wheel steering system in the Audi A8 allows the rear wheels to turn slightly in the opposite direction of the front wheels at lower speeds, making the car more agile and easier to navigate tight spaces. This is especially helpful for city driving and parking in tight spots.
