Definitely cool and more useful than the having to remove your wheels and attach tracks. It looks like rubbing might be an issue on some vehicles though.

Really neat, but so much is left out. How does it attach? There is some sort of link between the wheel hub and the contraption, but that doesn't look very strong. I also notice that never in the video does the truck make a sharp turn. That could be a major problem.
I'm also curious now the rotation of the tire results in the rotation of the tracks in the same direction. There must be some roller in between the tire and the track.
But I'll keep an ear out for more info.
