> Offhand, sounds more like most riding is with helmets My impression is: 1. Dutch-style utility riders using a bike to get around town for errands -> Rare helmets 2. Lycra-clad competitive cyclists with drop handlebars -> Widespread helmets 3. City cycle hire scheme users -> Rare helmets 4. Parents cycling with young children -> Widespread helmets 5. Poor people commuting on beat-up mountain bikes -> Rare helmets 6. Organised cycling events with mandatory helmets -> Widespread helmets 7. Teenagers riding with their friends -> Rare helmets So the popularity of helmets depends on your locale (does your area have utility riders?) - and whether you measure per-mile or per-bike-owner :)
