What is the function of the Audi A5's 'Audi drive select' feature?

I've heard about the 'Audi drive select' feature on the Audi A5, but I'm not sure what it does. Can anyone elaborate on its purpose and how it can be utilized?

Audi drive select allows you to customize your driving experience by adjusting the suspension, steering, and throttle response. For example, you can choose a more sporty setting for a dynamic ride or a more comfortable setting for a smooth cruise.

It's a great feature for those who regularly switch between city and highway driving, as it allows you to quickly adjust the car's handling to suit the road conditions.

I find that the 'auto' mode on Audi drive select is the best for everyday driving. It automatically adjusts the car's settings for optimal performance based on your driving style and road conditions.
