How does the Audi AI Traffic Jam Pilot work in the A8?

Can you explain the functionality and technology behind the AI Traffic Jam Pilot in the Audi A8? How does it handle stop-and-go traffic situations and what are the limitations?

The Audi AI Traffic Jam Pilot uses a combination of radar, cameras, and ultrasonic sensors to detect vehicles and objects around the car. It also uses map data and predictive algorithms to anticipate upcoming traffic situations. The system can automatically control acceleration, braking, and steering to manage stop-and-go traffic, but it does require the driver to keep a hand on the wheel and be ready to take over control at any time.
