Reminds me of the saying "Don't believe anything you hear, and only half of what you see".
I am extremely skeptical.
Is this a prototype or a real product? Not sure what I am seeing in the picture on the right, but it looks like some type of stabilizing wheel or roller under the platform - not real balancing technology. I'll believe it when I get to see and try one. Until then I will believe it is a piece of junk like the "Q" scooter is/was.
While I often ride my Segway with no hands and have learned how to make gradual sweeping turns by leaning, there is no way to really manuever without an "active" steering control.
