How does the Audi A3's self-driving feature work?

I've heard that the Audi A3 has a self-driving feature, but I'm not sure how it works or if it's safe to use. Can someone explain this feature to me in more detail?

The self-driving feature in the Audi A3 is known as "Traffic Jam Assist" and uses a combination of sensors and cameras to keep the car in its lane and at a safe distance from other vehicles while driving in slow-moving traffic. It's considered safe to use, but it's important to always remain alert and ready to intervene if necessary.
