You can opt not to use a toll road - but if you really
need to drive into London, you can't opt not to.
The current congestion charge requires no car-based
infrastructure so it's not a problem - but in a tag-based
congestion charge, you can't just turn away cars without
transceivers. There has to be an alternative somehow,
perhaps one which incentivises you to get a tag. Maybe
cameras will charge you a tenner if you don't have a tag,
but if you have a tag, your variable charge will
not exceed a tenner.

Why not just use cameras? I don't know what the road network is like in
Melbourne, but in suburban London the overground railways, rivers, parks and
segregated dual carriageways carve the suburban road network into a large
number of small sectors with relatively few links between them, and the
railways reach approximately to the existing central congestion charge area,
so you wouldn't need as many cameras as people might think. If all of the
cameras acted as a SPECS network as well, all of the speed humps and GATSOs
could be abolished.
