Firstly, I'm not talking about the blokes behind the lasers guns. I have noticed in NSW that while some areas are having their speed limits decreased outright(similar to the thread on Phillip Island), there is a lot of insidious "speed limit creep" ie. they don't change the speed limit, but they move where it starts and ends about 100m at a time on the slow side. I have really noticed it in the Blue Mountains where you can see where they have scarrified the old painted speed limits off the road surface. When in a 60, the 80 markings will be rubbed out and replaced 100m further up and vice versa when you come into a slower zone. It is happening all over the place. Another 100m of slower speed cannot have a direct effect on the road toll but I guess if you do it once a year, eventually you end up dropping the speed limit for the whole section. Which is obviously what they want to do but aren't willing to wear the outcry if they do the whole lot instantly.
