By the flawed 3D model I was reffering tothe 'theory' that the driver did it.
Although using a simplistic game model to simulate this is really taking it too far. The front seats where higher, as most theorists forget the car was modified before being used by JFK (strengthened etc...) the result of this were the seats were moved around a bit, front was higher and I think the back set nearest the trunk were shifted in some way as well but I'm working from memory here.
