Now the pilot only is able to rotate a steering wheel. Biped animation allows to make much more detailed animation. Shifting animation, pedals (accelerator / brake / clutch) animation, hand brake animation. That's what I mean. Then the cockpit would be a much more dynamic. PS sorry for my bad English...
its a nice "realistic" feature, however we dont really need to see the virtual driver's movements when we have our own. Especially if these movements are incorrect...they can throw you off and distract.
