While playing tutrial missions and scenarios I've noticed thta whenever I driver through some bushes I can see them in th driver's cabin. It happens to all the tracots I've played so far, that means the MB 1400, Claas Arion and Axion.
Also, in some of the tutorial missions when the "ghost" tractor appears to show you where to stop, its wheels are partiallly sunken into to the ground.
The third thing, is the driver not holding the steering wheel. It often happens when you look at him driving the tractor or harverster with his hands above the steering wheel, not touching it. But he still does the driving though. ;).
