How does the Audi A8's advanced safety features prevent collisions?

I'm looking at purchasing an Audi A8 and I'm curious about the various safety features it offers. Can someone explain how the A8's safety features work to prevent collisions?

The Audi A8 uses a combination of advanced cameras, radars, and sensors to constantly monitor the vehicle's surroundings. These systems can detect potential collisions and alert the driver through visual and audible warnings, allowing them to take evasive action or apply the brakes.

One of the standout safety features on the Audi A8 is its predictive Active Suspension system. This system uses a front camera to detect and prepare for potential collisions by lifting the side of the vehicle, providing additional protection for passengers.

The A8 is also equipped with an Audi pre sense system, which can detect potential collisions and automatically apply the brakes to mitigate or prevent the impact. This feature can even work at speeds up to 68 miles per hour.
