Oh my, new account coming right out the gate with this hot topic
Because it makes money, the vast majority of speeding fines are for under 10km/h under the limit enforced by cameras here in Victoria, that's why they dedicate so much resources to it.
You can't justify it in any way that doing 5 over the limit and having the fine issued weeks later from a camera is about safety - that's two thirds of the fines every quarter in VIC.
100% fake news,
Big hole in the VIC budget at the moment with $8-$10B/year in interest payments alone, with a government that owns no sources of revenue aside from speed cameras.
Good luck easier to set up a human colony on Mars than addressing that elephant in the room.
