There are a couple of points that need to be more closely scrutinized.
1. The document is titled safer journeys. How will increasing an ACC levy make the journey safer? Even if the levy were to double would that have a significant impact on the number of motorcyclists? The levy is just cost recovery and therefore in my view does not contribute to a "safer journey" and should not be an initiative.
2. From 2000 to 2008 the number of bike registrations increased by a factor of 4 . The number of casualties increased by a factor of 2. This is actually a significant reduction in rider/casualty ratio from 2000 to 2008.
What is needed is data showing the distribution of casualties per age group versus the number of riders within each group. I know that licence/age stats are available but that is somewhat meaningless.
The number of over 40 rider casualties does appear to be over represented but if they comprise the bulk of the riding community then it is what would statistically be expected based on probability.
I follow the 50/50/90 rule.
Anytime I have a 50/50 chance of getting it right there is a 90% probability I will get it wrong
