It's a neat idea, but I think it's of limited value in practice. Every time I've needed chains is because I'm properly hung up somewhere, and the wheels are spinning. At that point the vehicle is not moving forward and the chains (probably?) can't swing under the tire to provide traction. Who knows, maybe it would still work great. But I can't picture how that would work.
