What is Gesture Control Technology in the Audi A8?

I've heard about gesture control technology in the Audi A8, but I'm not sure what it actually does. Can you explain how it works and if it's worth investing in?

Gesture control technology in the Audi A8 allows you to control certain functions of the car, such as adjusting the volume or answering phone calls, with simple hand gestures. It uses a camera and sensors to interpret your gestures and activate the corresponding command.

I've found it to be a fun and intuitive way to interact with my car while driving. It's also a great feature for when your hands are full and you can't reach the controls.
