Hailing from Victoria I would have to say that I don't think our governments are really all that interested in saving lives. They say they are but they just make too much money out of their current policing of speed limits. Little if any of it seems to be injected back into driver training.
Its big business for them and they are now experts at making us (the average driver) feel unsure of ourselves and unsafe.
I just returned from California where the trucks have to stick to the right lane (slow lane over there) and have a separate speed limit. Most of the traffic was exceeding the 65-70 mph limit by 10-15 mph. The police didnt care in fact they were busy making sure the trucks did the right thing and slow drivers stayed out of the fast lanes. It worked incredibly well.
Driving back from Melbourne airport we were confronted with cars 4 abreast blocking all lanes doing anything from 80 - 95kph in a 100kph zone. It was just crazy.
They (our governments) need to put more controls in place for trucks and educate soon to be licensed drivers. Wiping off 5 may save a life. But instead of being told we should run into things as slowly as possible wouldn't it be better to know how to avoid running into them at all?
As long as they are including speed camera revenue in their budgets (and they do) there is little hope of changing anything IMO.
