Reduced speed limits on roads- exercise in futility

Roger from Ranui

The recent proposal to reduce speed limits on roads to increase safety will predictably be an exercise in futility, unless it is backed up by enforcement. Anyone who wants proof only has to drive the Northwestern causeway to town at 5.45am. The illuminated signs say 80, but almost everything is tearing along at 100. Yesterday I witnessed one driver travelling at 80, being overtaken and given the finger by another driver. And on one occasion a cop car buzzing along seemingly the pacesetter for the rest of the traffic- I was doing about 85 and he was going faster than that. Drivers are used to doing 100 in the past, and any reduction is simply seen as an imposition. Unless there is enforcement, and unless the enforcers also obey the rules, changing the signs and limits is a waste of time.
Far more effective is the installation of raised pedestrian crossings such as the one on Edmonton Road- when I went through yesterday everyone was slowing down to about 20 to go over it, as anything much over that speed would be practically damaging. Maybe there is the answer- road humps every 100m. Yes I am being sarcastic, but at least that would work.
