What is the point though? Those numbers don't indicate whether they wore a helmet or not, if they did what type, or whether the death was due to head trauma, and if it was head trauma, could the person have survived if wearing one.
America's high death rate on the highways is high for car drivers too! Maybe there is something wrong with the level of skill, the training, the enforcement, and curtesy on the road. Maybe there is something wrong when a 16 year old can walk into a dealer and buy a Hayabusa etc.
