How does the Audi A7 self-driving feature work?

I'm interested in purchasing the Audi A7 and I've heard it has a self-driving feature. Can you explain how it works and if it is reliable?

The Audi A7's self-driving feature, also known as Audi AI, utilizes a combination of sensors, cameras, and radar technology to constantly monitor the vehicle's surroundings. It can control steering, speed, and braking to help reduce driver fatigue and improve overall safety on long drives.

Audi's AI feature is constantly monitoring the vehicle's surroundings and can even make decisions in certain situations, such as changing lanes on the highway or navigating through heavy traffic. However, it is important for drivers to always stay alert and be ready to take over control of the vehicle if needed.
