Ho Individual !
They have already thought of that.
It has subsided out of sight.
Five minutes looking at the idea will show that there are so many ways
to bypass it that the enforcers could never keep up.
It can only work in a small area like Central London.
The system they use there could not be afforded if it had to cover
every street in every town in the country. So that is out.

Bazz,
In this day & age of GPS tracking etc. it should be one of the easiest & cheapest ways to enforce. You renew your rego every month or perhaps three months online & the thing is done. have random checks & if you're found cheating then you'll get hit hard enough not to ever entertain the idea of cheating ever again.

Re the GPS, all you have to do is slip a metal sleeve over the antenna and lo & behold no travel !
Alternative, just have a very low power oscillator on the GPS frequency.
If it was inside your car near the GPS it would never be heard outside.
The same with odometers, you just connect a signal generator to the
pickup on the transmission and run the odometer around till it reads
less than it was.

People are actually hacking the eeproms in the car computers.
The moment the car manufacturers introduced electronics they widened
the number of people that could fiddle their systems

Please tell me you don't expect people to get a $400K job for ZERO.
Bazz,
That's not an issue at all because technically it is no issue anymore plus the consequences of being caught are not worth the attempt.
Problem solved !

Oops ! I think I crossed a couple of threads here. Apologies.

Like rental housing, all levels of government see a tax milch cow in motor vehicles.

Through fuel taxes, higher registration costs and import duties government has sent such a strong price signal to motorists that the medium (eg Mitsubihi and Toyota) and larger vehicles (Falcon and Commodore) plummeted in sales. The car makers in Australia have closed their doors.

As an observation, the city snarl could be reduced a lot if cars were not part of salary packages and if public bureaucrats had to make some financial contribution to the fuel and running costs of the work cars they home garage. While on the latter, it is amazing how many public servants home garage and commute long distances to and from their country and coastal homes.

The other consideration is work sponsored parking. It strongly encourages commuting by private vehicle. Canberra public servants provide an easy example. Not satisfied with superb roads and ample parking, they want their parking free as well. For another example, a local State primary school where I am still called to volunteer in an honorary school council role has over ten years resumed larger sections of previous pupil play areas as teacher car parking. When my children attended, the thin edge of the wedge was the introduction of parking for the principal, then her deputy. Soon later there is bitumen everywhere and a procession of teacher and administrative assistant vehicles into the school grounds every day. Yet there is public transport right outside and the school grounds were declared as inadequate for the much lower student numbers twenty years ago.

This is the problem isn't it? That is OK for people to whine about 'others' and their cars, but they expect different treatment themselves. Sauce for the goose is never sauce for the gander. A person who could walk, take a bus or share a private vehicle takes a behemoth to a shopping centre carpark expecting others to leave their cars at home.

Some self-examination is in order because self-entitlement, selfishness to be blunt, and jealousy of others are now distinguishing features of Australian culture.
