Really? Cutting brakes on a pick-up. That would be a kick, seeing some poor old man pivoting his truck on his left rear tire outside of Furs, Hometown Buffet, (Enter your own all-you-can-eat), etc.
I think the concept of quadrasteer is a good thought. I am skeptical about adding additional complexities to pick-ups, but I have driven track-tractors, articulating loaders, and forklifts and all show that traditional lock-to-lock steering on pick-ups leave a lot to be desired. Hopefully GM can really get a quadrasteer out so that they can begin getting all of the reliability bugs out of it.
