Why.? Segways and motorcycles can be insured, what makes you think they are so unsafe..?I read an article not long ago that said that if motorcycles had been invented recently they would be banned from using the roads.
It's not necessarily about safety, but about whether it is useful.
By the very nature of its 10 mile range/10mph limit, this thing is being marketed as an alternative to walking, and thus need a bike lane or sidewalk.
Motorcycles drive in traffic lanes and follow the traffic laws. Very different.
Segways are also marketed as an alternative to walking, but they never really took off. NYC is arguably the U.S. city with the most heavy pedestrian traffic and you never see Segways. In fact, if some doof was barreling down the sidewalk on a Segway bumping into people or blowing his horn to get people out of is way, pedestrians would collectively pull him off the thing and kick his teeth in. I sense it'd be exactly the same with an electric unicycle.
