In considering this, there's also one group that's going to be quite interesting. As Waka Kotahi and those who administer this know, there is quite an industry in winding back clocks, or winding back the road-user charge mechanisms, and I just wonder whether an unintended advantage of this is that those individuals who habitually wind back the clocks—some of them even wind them too far. I'm well aware of someone who wound his clock back beyond the price of the previous purchase, which was pointed out to him by those selling the RUCs at the time. But I wondered whether an unintended consequence of this is that we may not have those wind-backs happening for at least the period of the three months.
