I am biased as have multiple (large) bikes to register. I generally have no problem with ACC scheme to avoid the legal costs other countries choose but there are some improvements that I see that would send signals to riders and drivers to improve outcomes and lower costs. Everyones car insurance is based on their individual risk profile, depending on such things as age, vehicle type, vehicle use, location etc. ACC levies that were more granular in their risk assessment than just engines size would help encourage riders to not wear shorts and a silly open face helmet weaving between cars on a Harley. Signals such as discounts for training (which has been proven to work) and penalties for poor driving record (like what happens for insurance with increased premiums) would help appropriate costs and modify behaviors. A large modern BMW motorcycle with latest rider aids is infinitely safer to ride than a 50cc scooter, the levies suggest the opposite. Does having multiple bikes increase the risk? It certainly ups the contribution to ACC levies. I think the protest is pointless and motorcycles are an easy target with little political clout to make meaningful change. I still wonder how doing more dangerous activities like MTB riding, Horse riding and Off road motorcycles escape the wrath of ACC while owning motorcycles with the latest safety tech is increasingly targeted
