Great looking image. In all seriousness, you should submit plans for those wheels to NASA/JPL as candidates for one of their rovers. Maybe duel independent wheels segments might not get stuck, or break down as much as a single one. Possibly, the wheels could be capable of bi-directional operation, i.e, forward and reverse. Additionally, if they had some type of gimbal arrangement, they could facilitate rotating 90 degrees, and move laterally out of a soft spot.
