I live around, and have ridden, some world class mountain biking trails. Helmets aren’t “lame”. The only choices are whether to wear a traditional helmet, full face, and body armour. This mentality of gear carries over to casual street riding around here. No gear = no money + blind stupidity. You see, it’s all perspective.
If ear buds had never been invented and you showed someone two similar looking models with the only real difference being one has a wire running down your body I’m suspect it would be the strange one. Perspective.
