Not to mention that, at least where I live, motorcycle helmets are penetration tested but bicycle helmets are not. This makes a big difference in effectiveness, but also weight and ventilation. Australia's mandatory helmet laws would not have been implemented if the pen-test standard was
not removed - meaning that to make helmet laws palatable to cyclists they made helmets less safe. Logical isn't it?
