I've never experienced this kind of behavior of anyone of my cars or BMWs I've owned. Not even the drama queen Ferrari does this.

Here are the parameters this usually happens. (7 out of 10 times)

Speed around 80+ mph
Freeway driving
HVAC A/C off, temp set slightly cooler than outside temp, fan speed one 1 bar, rear vent off.

At almost the exact same spot on the freeway plus minus 100 feet the HVAC fan would turn on full blast by itself for 1 second and then back to normal.

Doesn't matter which direction on the freeway I was traveling, but almost at the exact same spot.

Speed needs to be 80+, will not do this if below 80 mph.

Weirdest thing I've ever experienced in my life!
