How does Audi's automatic driving feature work in the A7?

I'm interested in buying an Audi A7 and I'm curious about the automatic driving feature. Can someone explain how it works and whether it's worth paying for?

The Audi A7 features an advanced automatic driving system that uses a combination of cameras, sensors, and radar to analyze the road and provide semi-autonomous driving capabilities. It can handle tasks such as staying in your lane, maintaining a safe distance from other vehicles, and even navigating through traffic.
