Cycling in Australia has significantly declined since the helmet law was imposed 20 years ago. Most casual cycling has disappeared. Fear, superstition, and ignorance, fueled by fearmongering campaigns like this one have scared most people off cycling.
Many people have had enough of a counterproductive policy whose main result has been to reduce cycling, at the detriment of health & the environment. A new movement called Freestyle Cyclists has been launched, with the aim of reforming this counterproductive helmet law.
You can join the movement and register your support at Freestyle Cyclists.
