Why does the Audi A8 have an adaptive air suspension

I've heard a lot about the Audi A8's adaptive air suspension system, but I'm not sure why it's necessary or how it works. Can someone explain it to me in simple terms?

The Audi A8's adaptive air suspension system allows for a more comfortable and controlled ride by adjusting the air pressure in each individual shock absorber based on road conditions. This helps to absorb bumps and keep the car stable on uneven surfaces.

In addition to providing a smoother ride, the adaptive air suspension also allows for different driving modes. In Comfort mode, the suspension is softer for a more relaxed driving experience. In Dynamic mode, the suspension is stiffer for better handling and control at higher speeds.

Another benefit of the Audi A8's adaptive air suspension is that it can adjust the ride height of the car. This is particularly useful for crossing obstacles or uneven surfaces, as well as improving aerodynamics and fuel efficiency at higher speeds.
