I'm an American currently living in Vienna, Austria, and I can tell you that scooters are probably the most common form of assisted travel here. They're used by men and women in business suits, children, Hasidic Jews - everybody. I saw a mother using two scooters to drop her children off at school: the older child had her own scooter, and the younger child rode with both feet on the mother's scooter. Closely following scooters in popularity are bicycles (some folders) and then long boards are a distant third.
