How does the virtual outside mirror on the Audi e-Tron work?

I heard the Audi e-Tron comes equipped with virtual outside mirrors. Can you explain how they work and if they are better than traditional mirrors?

The virtual outside mirrors on the Audi e-Tron use small cameras on each side of the car to capture a wider field of view compared to traditional mirrors. This provides improved visibility and enhances safety on the road.

In addition, the virtual outside mirrors also feature touchscreens inside the car to adjust the angle and zoom of the cameras for a more customized driving experience.
