Why do some riders not wear helmets?

Some riders believe that helmets limit their peripheral vision, which can make them feel less aware of their surroundings while riding. This perception can lead to a belief that not wearing a helmet allows for a greater field of vision, potentially making them feel safer or more alert to nearby hazards. However, it is important to note that helmets are designed to meet safety standards that minimize risks of head injury during an accident, and they actually offer protection that outweighs the concerns about limited visibility. In practice, wearing a helmet does not significantly hinder a rider's ability to see to the sides, and many modern helmet designs aim to maximize visibility while still providing safety features.
