well, a long time ago nicola and i developed the idea of giving the drivers-shape in the carshape a kind of upper arm in 3d. then the 2d arms should be moved as forearm to the driver, let´s say somewhere around at the elbow.
so the 3d upper and 2d fore arm can build almost a "real" angle, and they will "come up" from down (elbow) to the steeringwheel... it´s stll looking a bit funny but this could give an almost real effect (beside the steering wheel is 2d).
the most motion inside the arms when driving a f1-car is within the forearms, i think.
but to bring this, all shapers should go this way...
but...it´s hard to convince the people to produce their shapes in the same standard....
