There are many tangents to this discussion, and different approaches that might or might not improve things, but one thing that stands out to me is almost total lack of enforcement of existing traffic laws. I don't know what it is like in the big cities, but here in Hawke's Bay you have an excellent chance of getting away with not having a license at all. There is some enforcement of speed limits and we have the odd camera van that pops up here and there in addition to the usual patrol cars, and every now and then there is even an alcohol control, but I actually notice very little police presence here, especially on the many country roads. There are supposed to be some red light cameras but I don't see any evidence of people being ticketed on the spot. So lights get run, stop signs don't get stopped at, roundabout rules are ignored, and everyone pretty much merrily carries on as usual.
The problem is that successive governments try to do things on the cheap. There is very little police presence on the roads, and almost zero enforcement. If you want to change bad behaviour, there have to be immediate painful consequences to doing the wrong thing. At the moment that is not the case, and the occasional blitz won't change that. If there are traffic patrols everywhere, and near-certain penalties for breaking the rules, things will change. Otherwise not.
