Walking car design proposed

Hyundai developed a 'walking car' and 'unveiled' it at the CES trade show yesterday. As far as I can tell it's just a mockup video, but the idea is timely. Traditionally, only flimsy and obviously impractical spider-legged robots could handle rough terrain, while two- and four-legged ones were too unstable to get far. Will Boston Dynamics soon have serious competition? Add your thoughts in the comments, increasingly-useless waterlogged meatbags!
