Rego will NEVER cover the costs.

The motor vehicle is just too simple a (tax structure) to let it go gentle in the good night.

The will be a massive hole that will need to be filled.

So increase the ICE costs to a diminishing base or tax the new kids on the block (or increase the GST for all & sundry). your choice.

If you are looking to move to electric cars for the CO2 reduction to save the planet - good luck with that.
There is debate as to is actual value in CO2 reduction cradle to grave (& if the savings are so nominal why bother & it certainly is not a clear cut winner)

If we really want to save the planet - why not just give billions of dollars to the lungs of the planet.
We already have a carbon sink in Amazon & Congo (et al jungles). Just stop them cutting down the tress for economic value. Would be cheaper.

In you are on the electric band wagon then I welcome you to the support for Nuclear power stations to save the planet as there is no other viable alternative.

Bureau of stats say the income was at $27b (& shrinking). We either have to replace this or reduce living standard (FWIW this money is not JUST spent on the roads).

Possible solutions

Infrastructure Australia recommends reform to the whole system; that is, that all existing government road use taxes and charges be removed and replaced with ‘direct charging that reflects each user’s own consumption of the network, including the location, time and distance of travel, and the individual characteristics of their vehicle such as weight and environmental impact.’
This system is also recommended by Infrastructure Partnerships Australia, which says it ‘offers strong opportunities to rationally price access to, and usage of, the road network—providing a mechanism to fund network additions, fund maintenance and improve network performance by aligning supply and demand.’ Australia motoring lobby group, theAustralian Automobile Association is in favour of this reform.
Other policy options include the introduction of zone pricing, particularly in cities, and corridor-specific charging.
Zone pricing

Zone pricing (also known as a congestion charge or tax) charges road users to use certain road systems. Zone pricing has broad support from economists, and has been implemented in a number of places, notably in London, Singapore and Stockholm.
Corridor-specific charging

Corridor-specific charging, works in the same as city toll roads. A fee is levied on users who access a particular road, much the same way as a toll road, except the corridor may be publicly, rather than privately, owned.
