A vehicle wiper park mechanism includes a shutoff gear that turns at half the speed and substantially diametrically opposed interrupts that are interconnected randomly, with approximately equal frequency, to park the wipers. The interrupts are offset from an exact diametrical opposition by an angle sufficient to assure that the wiper blades will be randomly flexed in opposite directions when parked, thereby avoiding a permanent blade set with time.
