This is a major issue in single- and multiplayer as it happens multiple times during a two hour sitting when driving any tank.
I was ripping my hair out when debugging a custom vehicle only to notice that all vehicles are affected. I think this bug started at some point during 1.48. It happens on dev branch too, it did at least some days ago.
AI are affected equally.
Reproduced so far with: T100, Sochor, Kamysch, Tigris, Kuma and Mora.
