Do I understand you correctly that hitting a wet mud road with VSC+Traction turned on makes the car slide more than without it? I've only used the Commodore with TRC in the wet and believe it to be very good for inexperienced drivers. Actually, here in Saudi Arabia, we have dry heat or dry cold, so the maximum you get are sandstorms in the extreme heat of June-August and rainy season for 2-4months between Nov-Feb. So, over here VSC/TRC is only useful during the winter if it rains.
