It's called TAX...this has nothing at all to do with road-safety and is liable to cause more accidents than it prevents.
You add this to your PAYE, PAYG, GST, Stamp duty (houses and cars), fuel excise, car rego, city link tolls, parking meters, parking fines etc etc etc and you try to live on what you have left and hope there is enough left over to fix the damage done to your car by stones and bad roads cos "they" aint responsible (the only good road in the state is city-link) and we must all be terrible drivers otherwise they wouldn't need the cameras...right? When u think that everything you do costs money and a tax of some sort, where the hell does the money go ?!?! Why can't they put some back into driver education so that we are all actually safer?
