at the end of the day, motorcyclists in this country as a group cost more to fix & longer to rehabilitate from injuries whether it was their fault or not simply because of being on a bike.
I grew up on bikes as did all my dads side of the family, they were bikies around Chch. two of my cousins are amputies & my uncle has spent years on ACC from bike injuries & i choose not to ride on the road as i see it too risky by looking at my family. Thats my choice & therefore i don't have to pay for that directly but those who choose to need to help with the costs created by this pleasure. I am sure that if you are injured (i hope you never are) you will appreciate the services you will recieve to fix your injuries but that does come at a cost.
& for the multiple rego's, we all pay rego's on multiple cars whether we drive them or not.
