How do bike helmets promote a safe and responsible cycling culture if the emphasis on helmet use alone has the potential to overshadow other crucial safety measures, such as improved infrastructure, vehicle awareness, and adherence to traffic laws, and does the widespread adoption of helmets inadvertently contribute to a societal safety paradox where increased perceived safety leads to more reckless behavior among cyclists and a false sense of security among motorists, thus potentially undermining the effectiveness of helmets as a safety tool in the broader cycling ecosystem?
