Like Paul Graham said in July 2009[1] The trouble with the Segway is that it makes you look smug. This thing will make you look even more so.
I think the people in this video look smug, for various reasons unrelated to the U3-X itself.
It looks like this only targets indoor super smooth surfaces, but I think it could definitely find a niche.
I wonder if it could handle a skateboard park in some way?
This thing has you sitting down so its ok... Closer to other riding vehicles
