You’ve seen the LIKE A ROCK (and a hard place) ads where Chevy touts its new Quadrasteer system. The PU truck has rear wheels that toe in – toe out as needed at low speeds to tighten the turning radius. Their demo shows a horse trailer on a ball hitch being maneuvered into a really tight one. Anybody that’s ever wheeled a trailer knows how difficult this can be and that’s with conventional steering. Try backing one up with all wheels articulating. Complex task. Come to think of it, the professional driver / stunt man never demonstrates the entire maneuver… Hmmmm
