I think the creator is just trying to promote it to make himself money. Sure, it's neat, but it's hardly going to revolutionize the way cities are designed.
-Cities are NOT going to ban cars yet allow gyro-scooters. For one thing, it'd be mighty inconvenient to make the delivery trucks stop at the city limits. Also, in my car, even for a short trip, I can carry four other people. Try that on a Seguay. No, maybe all my friends aren't going to buy scooters of their own...
-Property owners would probably not let these things inside their buildings.
-It costs nothing to walk to work. It costs $3,000 for a Seguay, which is about three times what my car is worth. It isn't going to replace pedestrian travel.
-Where are you going to leave it when you go into McDonald's? Chain it to a bike rack?
-Cities are already designed to accommodate cars. They're not building any new cities from scratch, so I doubt we'll be seeing any roadless paradises anytime soon.
I'm not saying it's not cool or anything, but due to its cost and the fact that it's still a vehicle, you won't see it replacing cars. And becuase it costs three grand, it certainly won't replace bicycles, especially among financially-challeneged college students.
