It's a bit tricky because being properly subjective and trying to nail it with a quick internet take are at odds with each other, but here are some ideas.
- Pose is strange in terms of analog to the general evolutionary catalog of human poses; it's like the rider is delivering a tray of drinks. Leaning forward is also considered to have a conciliatory effect, as opposed to something more like the unconcerned cool effect.
- Stance is not dynamic (bicycle) or fluid (car/train riding)
- Static movement effect. The proportion of visible moving parts (size of wheels in proportion) to visible static human body parts is out of balance. Cars and most motorcycles are way better than this for example. And imagine if (armor concerns aside) an F-35 flew by, and you just saw the pilot laying there at full stretch under the canopy. It's a much different effect. In movies it's used for conveying vulnerability, e.g. stasis pods in Alien.
- High proportion, combined with no mass-thinning effect at extreme of height
- In general, this all goes against nature in a good way (that shouldn't work mechanically), but it also goes against nature in a bad way (humans look for natural looks to determine what's cool, so they give it a kind of fail)
With all that said I personally don't find the segway uncool, nor am I in line to own one...
