Drove along there yesterday... bloody shocking! Be much better off with a low smooth asphalt bump... same effect but without the added effect of pissing off drivers. They have those big rubber things up near my house. PITA!
There is some company going round Perth convincing councils to put down these monstrosities everywhere under the guise of "road safety". We had a council meeting about "road safety" last year to discuss what could be done to make the local roads safer. We thought we'd be talking about pretty median strips with trees etc but what the meeting was really about was the company making a pitch to put these mats down on the road!
Conspiracy I say! haha
