fixed axis for steering joint and gas and pedal joints. 1) the axis for steering seemed to be specified in body frame as opposed to joint frame, which doesn't make sense. Also the prismatic axis for gas and pedal joints seemed arbritary, I changed them so that the pedals translate along the longitudinal direction of the car. But ideally these should be consistent with the model that osrf provides, but i suspect they have done a hack job on this.
