I used to regularly drive along an outer Melbourne road with a posted limit of 100km/h. They(?) changed it to 80km/h without any changes to the roadway, new housing, or the surrounds etc. Anyway, I didn't even realise it'd changed until one day my infrequent passenger said, "ferk me, look at that, a lower limit". I dunno how many times I'd driven along that stretch of road 20 kays over the limit LOL.
So... how can a road be considered safe at 100 one week, but only safe at 80 the next week? Doesn't this prove the revenue raising claim is true?
Lowering the speed limit on roads in Qld is the easy way for the gov't to make unsafe roads safer. Instead of fixing/repairing/rebuilding the road they just lower the limit - saves them spending money and also increases the coffers with more fines!
