Why does MSFS LOVE LOVE LOVE photobombing scenery with vehicles?

Seems 75% of the time or more, I add some objects to scenery, MSFS decides it’s a super-awesome idea to throw some scenery right in there with mine. Ground vehicles loiter HARD.

So, here’s a scene where I placed a few people on an otherwise desolate ramp - and suddenly, there’s a plane parked RIGHT IN FRONT OF THEM and a ground vehicle that circles then just invites itself to park.

Is there a way to make MSFS knock it off?
