Robert MacNeil hosts a discussion about the growth in the moped industry in the United States for The MacNeil/Lehrer Report. In this instance, a moped is defined as a vehicle with both a motor and pedals, which leads to difficulty in classifying it as either a bicycle or a motorcycle. Discussion centers on the possibility of State mandated regulations like a minimum age or testing and licensing drivers and safety concerns, specifically wearing a helmet and the issues of visibility when a moped driver is in the flow of traffic. Maintenance concerns are also addressed; there are few mechanics able to service mopeds because the industry is relatively new.
