How does the Audi A1's self-driving feature work?

I am interested in learning more about the advanced self-driving technology in the Audi A1. What sensors and systems are used to allow the car to navigate and make decisions?

The Audi A1 uses a combination of radar, lidar, and cameras to constantly scan its surroundings and create a 360-degree view of the road. This information is processed by the car's computer to make decisions and adjust its driving accordingly.
