There've been tweels and other airless designs for decades. I would have liked more real footage and less computer generated animation. I noticed that on the one glimpse of real footage, they only had their invention on the right rear. I'm having a hard time imagining all those bolts transmitting torque, especially braking torque, and not wearing out all sloppy in very short order. The Tweel doesn't have sliding moving parts like that, only flexy elements. BUT, it would be nice to see them make something like this work. God knows keeping tires aired up is too taxing for today's motorist.
