What is BMW's gesture control feature and how can it be useful?

I've heard about BMW's gesture control feature, but I'm not sure what it does and how it can be beneficial while driving. Can you explain it in detail?

Gesture control is a unique feature in the BMW X2 that allows you to control various functions of the car by using hand gestures. For example, you can adjust the volume of the music or answer a phone call by simply gesturing with your hand.

This feature can be especially useful while driving as it allows you to keep your hands on the steering wheel and your eyes on the road, minimizing distractions.

I've personally found it to be a convenient feature, especially when my hands are full or if I'm wearing gloves during colder months.
