Nismo and the Suction pipe.
In NSW yes it is friendly..
I did a trip from Albury to Stanly and drove past 2 road side radars and did not even know it as they are in unmarked cars (RAV4) and no signage.. VIC government should be ashamed, that is blatant revenue raising as there is no safety aspect to it.
About time the VIC people stood up to the Government and tell what they think about their behavior.
