How does the Audi A8's advanced safety features protect against rear-end collisions?

I've heard that the Audi A8 has a variety of safety features, including some that specifically help prevent rear-end collisions. Can you explain how these features work and what makes them stand out from other car models?

The Audi A8 is equipped with a pre-sense rear system, which uses a rear-mounted radar and camera to detect potential rear-end collisions. This system can automatically apply the brakes to help minimize the impact or even prevent the collision altogether.

In addition to the pre-sense rear system, the Audi A8 also has a cross traffic assist feature. This uses the same rear-mounted radar and camera to scan for vehicles approaching from either side when you are backing out of a parking spot. It can provide visual and audio warnings to alert you of any potential hazards.
