I am not talking about mopeds but children’s two wheeled push along toys. They are called ‘trottinettes’ in France. They are a method of personal transport that is not the sole domain of 6-year olds. Parents might use one to make the return journey from school more rapid. Businessmen use them on the streets of Paris. Teenagers do stunts on them at skateboard parks. One of my adult business students arrived at a lesson with bruises and scratches. He had been riding on one and hit an uneven bit of paving. I’ll keep to my bike! Now of course there are electric versons of these being used on pavements!
