Good question.
When I used mouse steering in AC, some mice had a similar issue where the steering wheel would randomly flip to one end of the max rotation, making me lose control.
I didn't even use freepie or anything, just the native, inbuilt mouse steering.
It went away when I bought a new mouse. For whatever reason.. Both Logitech, both their own lightspeed wireless connection. G703 had the issues, the new "G pro superlight" does not.
