hmmm, good on the yanks. All we need to do is send Anna Bligh and Julia Gillard over there and we'll have it in no time too!
Seriously though, it's all a joke. "Ever K over is a killer" - what an insult to our intelligence! They flip speeds all over the place at a whim.
Traveling the Bruce Highway between Bris and Sunshine Coast, I reckon 50% drive at 110 (speed limit), 10% drive at 100, and the other 40% sit on 110-140. The thing that they all know is that the traffic can travel quite safely and comfortably at least at 130 without any problems along that stretch of road. Of course the other interesting thing is while there are accidents, most I come across are single vehicle and I bet are due to lack of concentration but are reported as speeding. And just as they always do report as speeding for the stats to justify increased surveillance and fines to guarantee a now massive income stream, it has absolutely nothing to do with safety - you only have to look at where QLD positions it's fixed camera's. High speeding potential (= high revenue), but often low accident risk - go figure! It's just so easy for the government to jack up the fines and improve the technology in order to increase the chance of getting fined, because it's such an emotive issue and so easy to sell to the generally lame population (present company excluded).
sorry - end of rant.
