> Risk compensation is fascinating; driving with a bike helmet causes the biker and drivers around the biker to behave more dangerously.

Do you have a truly reliable source for that? Because I hear this statement once in a while, and it feels flawed.

A helmet protects you from severe head injury if you are in an accident. There are more reasons for accidents than reckless car drivers. For example:

- Bad weather

- Driver not seeing the biker at all (no matter with or without helmet)

- Crash between 2 cyclists
