After waiting a while, he decided to play it safe and drove off.
That is an exception.Often it does not go away on its own. And besides, loose objects can’t go away on their own. So it remains a difficult side issue. Fortunately, in FS2020 you can simply drive over it without any nasty consequences.
Hopefully this little problem within the really great sim will be resolved soon, making FS2020 more realistic.
