I think we all(car people)know how to fix most of our so called problems,i'd also suggest a good many pollies would also know,but the bottom line is that they(pollies)don't want it fixed cause it generates too much income to be messed with.This may sound cynical but consider for a moment the funds pumped into consolidated revenue thru the motor vehicle usage within our states and teritorys.

Until a replacement tax is dreamed up nothing will change except the fines will keep increasing.A classic example of my theory is Australias water usage,we are all told to use less water as we hav'nt enough to go around,so being good citizens we all turn off,kill the grass and gardens and generally make do with less.Congratulations say the authorities you have done well,however as our fixed costs for running the water grid have not changed and you are using less we will be charging you more for each litre you use so our margins can be retained and our public service sector maitained at an increasing rate.
The most recent car/driver safety talkfest held in Brisbane a couple of years back had all the boffins in attendance plus several other well meaning speakers,including Dick Johnson (like him or not)armed with all manner of ideas/concepts/facts...he and others where basically laughed out of the talks...by the end of the talkfest the only tangable thing to come out of it was an increase in fines to the then Beattie government and now kept alive by constant auto related increases by our very own Capt.Bligh.
Yep that'll fix it
