I think this is because of the “clearly not a toy aspect”. Riders often are wearing full motorcycle helmets, pads, and rash guard gear. It people geared up that way on other boards/scooters there would be less injuries too. I had no protective gear which was a mistake. I didn’t fully appreciate how speed would compound the impact if I took a spill. Honestly thought it very unlikely I would fall at all the day I did. I was taking a ride on a route I already knew very well.

I also think the initial difficulty of unicycles acts as a good filter so that people with subpar abilities simply don’t try. The rentable scooters are dangerous because people that shouldn’t be on them have a false sense of ability because it seems easy. Until they get to speed or take their eye off the road or something.
