I never realized how fast 25mph was until I fell off my two wheeled electric scooter going that speed and was slowed down by a bus-head impact after I braked a bit. Luckily I was wearing a helmet and long pants, but I still broke my back in several places. A cop that saw me whiff it said I was probably only going 10 by the time I hit the bus.
I believe all of these electric whatever should be lawfully mandated to go below at least 15mph if not lower. I don’t believe that people are able to grasp just how unsafe those speeds are.
