What is the difference between the Audi A8's Comfort, Auto, and Dynamic driving modes?

I've noticed that the Audi A8 has three different driving modes - Comfort, Auto, and Dynamic. What are the specific differences between these modes and when should I use them?

The Comfort mode optimizes the A8's suspension and steering for a smooth and relaxed driving experience. It's great for long trips or city driving.

The Auto mode adjusts the A8's settings based on your driving style and conditions. It's perfect for everyday driving and provides a balance between comfort and performance.
