The greatest risks to scooter users are collisions and falls. If a user is negligent and dashes out into the road, he or she can be hit by a car or cause a collision between other vehicles. It is also possible that someone using a scooter on a sidewalk will crash into a pedestrian, a building, or other stationary objects. Over the past year, as outdoor dining took up more and more space on sidewalks, it was difficult enough to move around. Adding a scooter to that mix could be injurious or fatal. Falls from scooters can also increase the risk of serious injury or even death. A person moving at 20mph on a scooter lacks any type of protection in the event of a fall, and could easily break a bone, suffer head or brain trauma, sustain “road rash,” or cause him or herself permanent harm to the neck, back, or shoulders. If the road, trail, or sidewalk has debris on it, or if there is a pothole or uneven section of pavement, the risk of a fall may be imminent. In addition to the increased likelihood of being knocked over and falling from a scooter accident, pedestrians complain that the scooters increase sidewalk congestion and that vandalization of the shared scooters is creating health concerns and beautification concerns.
