Episode notes
Risk Compensation with Helmets
- Helmets likely reduce head injury risk if a cyclist crashes, but may cause compensatory risky behavior.
- Risk compensation means some cyclists might cycle more dangerously when wearing helmets due to perceived safety.
Drivers Pass Helmeted Cyclists Closer
- Drivers tend to pass cyclists wearing helmets more closely, possibly perceiving them as more skilled.
- This closer passing could increase risk to helmeted cyclists despite their protection.
Limitations of Helmet Protection
- Helmets protect against linear head impacts but might worsen rotational brain injuries due to increased torque.
- Most cyclist deaths are from crushing by large vehicles, where helmets offer little protection.
