I’ve played with the 0.9 RC and had the same bug.
My character had bug under his right arm and he was scraping it while driving.
Every step the error appears again, until I was back in the vehicle.
But where the controls were sat a different self. Sorry, I have no pictures now.
I’ll try to reapplicate the errors.
Another bug with vehicles is:
If you grabbing a shopping-car or another similar vehicle, go on the first tile of another vehicle and then back with pushing the shopping-car. The game says, that it can’t find the vehicle, but no problems remain.
