What are the advanced safety features in the Audi A7 and how do they work?

I am considering purchasing an Audi A7 and I have heard about its advanced safety features, but I am not sure how they actually work. Can you provide some more information on these features and their capabilities?

The Audi A7 comes equipped with a variety of advanced safety features such as adaptive cruise control and lane departure warning. These features use sensors and cameras to detect potential hazards on the road and warn the driver or even automatically take action to prevent accidents.

One of the standout safety features in the Audi A7 is the night vision assistant. It uses thermal imaging to detect pedestrians and animals on the road at night, giving the driver more time to react and potentially avoiding a collision.
