The grounding shield can be formed of cylindrical shielding member 15 made of metal wires, metal strips, or a cylindrical metallic member having a perforation of a plurality of small holes thereon. A first compliant linkage element has first and second ends and is disposed between the first and second rib portions of the rib element, the first and second ends are each coupled to the interior of a respectively associated one of the first and second rib portions. The change in yaw moment can be determined based on a reduction of lateral force on a driven axle due to both longitudinal and lateral slip on the driven wheels.
