What is the purpose of the Audi A3's Progressive Steering system?

I've heard that the Audi A3 is equipped with Progressive Steering, but I'm not entirely clear on what it does. Can someone explain its purpose and how it differs from traditional steering systems?

The purpose of Audi A3's Progressive Steering system is to enhance the vehicle's handling and responsiveness by adjusting the steering ratio based on the steering angle and speed. This allows for smoother and more precise turns while driving at both high and low speeds.

In traditional steering systems, the steering ratio remains constant, which can result in over or understeering. However, with Progressive Steering, the steering ratio becomes more direct as you turn the wheel, providing better control and stability.
