Those are great!
Distractions, it seems like they can lower your IQ by, like, half or so.
When I place some AI planes in X-plane and they constantly talk sh** on my channel, and among them is the ATC, spelling my registration number wrongly (**** dammit it is pronounced “LEE-MAH” not “LIE-MAH”, and nobody ever says “sevenhundred-and-fourty-seven-to-eight-hundred”) I noticed that even simple tasks like starting up the plane or taxiing on the right taxiways can become a hard task, let alone navigation.
And then one of my children may come and ask something or the cat may jump onto the desk, and I have to pause the sim. I just cannot work like that!
