What is the Benefit of Using Audi Pre-sense in A4 Vehicles?

I've heard of Audi Pre-sense, but I'm not sure why it's important in an Audi A4. Can you explain its benefits?

Audi Pre-sense is a safety system that uses sensors and cameras to detect potential collisions and take action to prevent or mitigate them. This not only helps protect you and your passengers, but also reduces the risk of costly repairs in the event of an accident.

By constantly monitoring your surroundings, Audi Pre-sense can detect hazards and warn you through audio and visual alerts. It can even initiate emergency braking if necessary.

In addition to collision avoidance, Audi Pre-sense also includes features such as blind spot monitoring, rear cross traffic alert, and exit warning to help you stay safe while driving.
