Why is the optional dynamic all-wheel steering system important for the Audi A7?

The Audi A7 comes with an optional dynamic all-wheel steering system. This allows the rear wheels to turn up to 5 degrees in the opposite direction of the front wheels at low speeds for better maneuverability, and up to 2 degrees in the same direction at higher speeds for improved stability. But is this feature really beneficial? And why is it specifically important for the Audi A7?

The optional dynamic all-wheel steering system is definitely worth considering if you're someone who does a lot of city driving. It greatly improves the turning radius and makes parallel parking a breeze.
