There is NO WAY I would ever ride that thing. First of all I could not afford to keep resoling my boots. It looks like that episode of the Six Million Dollar Man where Steve Austin stops a car by dragging his feet. And everytime you ride it you need a minimum of FOUR other people just to help you get set up and rolling. And there is NO suspension meaning every bump and dip in the road goes straight to the "Wheel Chassis" or whatever you call that thing. If he hits a dip or bump while "braking" by dragging his feet he will snap his ankle and get yanked off that thing.
I'm all for inventions and new stuff, but just because you can, doesn't mean you should.
