And the second point is: if we're going to put this particular section in, why are we not asking for this to be done on a frequent, regular basis? At the moment, with the terminology being "may", this could be done once a year; it could be done never. It could be done, for instance, in three years' time. Surely this would be something that should be monitored on a regular basis. And I know there are some reporting requirements, but reporting requirements are very different from the monitoring and reviewing requirement from the Ministry of Transport, which I would be suggesting would be an important amendment or change that the Minister may like to consider.
