How does Audi's AI Traffic Jam Assist feature work in the A8?

I'm interested in purchasing an A8 and I've heard about the AI Traffic Jam Assist feature. Can someone explain how it works and if it's worth the extra cost?

The AI Traffic Jam Assist feature utilizes sensors and cameras to monitor the lane markings and surrounding vehicles in slow-moving traffic. It can control acceleration, braking, and steering, keeping the car centered and a safe distance from other vehicles. This feature lessens the strain of stop-and-go traffic, making your commute more comfortable and less fatiguing.

I've used this feature multiple times and it's definitely worth the extra cost. Not only does it make driving in traffic less stressful, it can also improve safety by preventing rear-end collisions. Plus, if you upgrade to the top-of-the-line InnoSound system, it will even play relaxing sounds to further reduce your stress levels.

I've had some issues with the AI Traffic Jam Assist feature, specifically in heavy rain and bright sunlight. In these conditions, the sensors and cameras can become less accurate, leading to momentary disengagements. However, overall it still provides a smooth and convenient driving experience.
