I've seen a lot of these one wheeled electric unicycles in my home country whizzing along at pretty fast speeds (35kph++) on multi use paths that have people on bicycles, roller blades, walking, and running. Most of these people are kitted out in a full face motorcycle type helmet, long sleeve jacket, gloves, knee pads, and elbow pads, along with gloves. Most seem to obey the most basic of rules and really don't cause any problems.
