I just saw this and was kind of intrigued. I use a Burley Travoy frequently, but the idea of being able to ride without towing to a store and just deploying for the ride back seems kind of cool. It also fits folding bikes (which mine are). I'm sure there are flaws and reasons this is a bad idea, lol, so please chime in.
