Should Segways be allowed on sidewalks? Should all bicycles travel only in designated bike lanes? Should motorized scooters be treated as if they are wheelchairs? Where should rollerblades, skateboards, adult tricycles, bikes with trailers or kick scooters travel? The world of personal mobility is expanding.
