How does the BMW iVision use Virtual Exterior Mirrors?

I've noticed that the BMW iVision does not have traditional side mirrors. Instead, it utilizes Virtual Exterior Mirrors. How exactly does this technology work and what are the benefits of using it?

The BMW iVision uses cameras to capture the surroundings of the car and displays it on screens inside the vehicle. This eliminates blind spots and provides a wider view of the road.

Using Virtual Exterior Mirrors also reduces drag and improves aerodynamics, resulting in improved fuel efficiency.

Personal advice: get used to the new placement of the screens and adjust them to your preferred viewing angle. It may take some getting used to but it's definitely worth it.
