In cockpit view his thumbs are on the inside of the steering wheel. One of the first things you learn when driving off-road is to keep your thumbs on the outside up by your fingers. That way when your tire hits something and the steering wheel is jerked you don't risk breaking your thumbs.
@derek-b Oh ok I understand.
I had car accident. I hit tree straight on with my hands on the wheel at about 40kmh.... My thumbs was fine But my middle finger hurts after that Weird :p
Anyway maybe in the future they will add such details.
As for now there are other funny bugs. My driver was asleep while driving UAZ! Seriously he used his mind to controll vehicle. Its that he is so awesome he dont need to use his hands at all or even watch to drive!
