How does the Audi A8's adaptive air suspension improve ride quality?

I've heard that the Audi A8 has an adaptive air suspension system. Can you explain how it works and how it affects the car's performance and ride quality?

The adaptive air suspension in the Audi A8 uses air springs and electronically controlled dampers to adjust the car's ride height and stiffness. This allows the car to adapt to different road conditions and provide a smoother and more comfortable ride. As someone who has driven an A8 for years, I can attest to the improved ride quality over traditional suspension systems.
