I genuinely do not believe any OneWheel riders are in this category. Loads of things aren't safe and we still let people ride them. I don't have a OneWheel, but my friends and I have beat those light-up speed signs enough times on bikes, longboards, skateboards, you name it.

It's fun as fuck, and maybe you can die so you should wear a helmet but preventing people from playing with death is bullshittery.
