Hoverboards and Segways are not good for transportation because of their wide footprint. You need to be constantly watching the path of the wheels on both sides of your feet. The wheel on the right may hit a bump you just don’t see, and then you may get precariously close to the edge of the curb on your left. If you hit something, you can make the vehicle spin, which could throw you off balance. The Iota eliminates these hazards. Because the wheels are between your feet, you only need to scan the road directly in front of you, making it genuinely useful and practical.
