How does the Audi A8's self-driving feature work?

I've heard that the Audi A8 has a self-driving feature, but how exactly does it function and what limitations are there?

The Audi A8's self-driving feature relies on a combination of sensors, cameras, and algorithms to maintain lane control, adapt to traffic conditions, and even park the car without driver input. However, it still requires the driver to remain alert and ready to take over control at any time. So while it may provide some assistance, it's not a fully autonomous feature.
