I wouldn't mind seeing a greater rego fee for larger vehicles - ie a kerb-weight based tax.
Would discourage people buying Landcruisers for the sake of it... also a regular licence test/renewal system would be good, perhaps even varying levels of licences - one for city/urban driving, one for country driving, one for freeway driving (or something).
Just thoughts...
And as Snowy says - it's sad that the Govt disguises revenue raising as 'road safety'. I think some form of justification for camera placement would be good, show that the government is actaully trying to lower the road toll (which they haven't) instead of just wanting to line their pockets.
The whole thing needs to be reviewed... Snowy for PM!
