How does the Audi A7's Active Lane Assist work and how reliable is it?

I've been considering purchasing a new Audi A7 and have heard a lot about its Active Lane Assist feature. Can someone explain how it actually works and if it's trustworthy enough for daily use?

The Active Lane Assist feature in the Audi A7 uses cameras to detect lane markings and will automatically adjust steering if the car begins to drift out of its lane. It's a reliable safety feature that can be a big help during long drives.

In my experience, the Active Lane Assist works very well on highways and well-marked roads. However, it may struggle on more rural or poorly marked roads. It's still a useful feature, just be aware of its limitations.
