Road taxes should be directly proportional to how much wear a vehicle causes to the road. That ranges to effectively zero for bikes and pedestrians to dozens of times as much as a car for eighteen-wheelers.

Further, large trucks don’t travel on many roads, which are useful roads to people throughout suburban and rural areas. These roads need maintenance too, even if the wear is more from weather. As a car owner, one has to participate in maintenance of the system somehow.

The vast majority of road damage is done by heavy trucks. Don't need to tax these cars at all.

But you still need to maintain existing and build new roads, and not only trucks drive on the road. What about snow? It needs to be removed for normal cars as well as trucks.

Snow removal is probably different, but the point is that road maintenance due to regular road wear would be significantly (perhaps at least an order of magnitude) less if there were only passenger cars on the road.

I'm not really sure there's a good answer here. Fuel tax is 43 cents a litre. Australian cars right now avg about 13.1 litres per 100km. So you're looking at ~$5.6 per 100km for fuel tax. This tax is adding $2.5 tax per 100km for electric. Right now, EVs are absolutely creating an regressive tax situation with regards to fuel. Those who can afford to buy newer, efficient cars can usually save money on tax over those…

I read somewhere that road damage caused by vehicles is not linear with weight. Heavy vehicles do much more damage. I can't cite a source, but I recall an exponent between 3 and 4 on the leading term. With that in mind, everything but heavy freight is basically negligible. And then it's generally for businesses where privacy isn't so much of an issue.

A lot of road damage in some parts of the world is caused by nature itself, though. Even roads without any freight traffic get frost heaves.

This is true, but some portion of road maintenance costs is independent from vehicle-caused wear-and-tear on the actual road surface. You would want this portion to be paid also by standard, non-commercial vehicles since these users are clearly receiving some value from the existence of a well-maintained road.

As a European, 13.1 l/100 km seems... insane. What's happening here?

Has to be including heavy vehicles?

Australians still by V8’s but not that many of them can be...

Everyone benefits almost equally from the road system, regardless of whether they drive. Emergency services, food and other goods, the entire economy depends on the roads. Taxation to fund road maintenance should be central and universal, and not directed at individual vehicles, other than perhaps a sales tax based on weight.

That sounds "fair" but amounts to a massive subsidy of diesel powered heavy trucking.

TBF, it is possible to build roads that trucks do not quickly destroy, and maybe the expense of doing that makes sense in some cases.

Everything except heavy trucking would pay much less to maintain roads, but for trucks wearing them out. While you suggest a tax based on vehicle weight, which might also seem "fair," that still does not capture the disproportionate wear, order of magnitude more, caused by heavy trucking.

Fourth power of the axle weight.

Wikipedia says damage is proportional to axle weight to the 4th power: https://en.wikipedia.org/wiki/Vehicle_weight#cite_ref-13

Every car has an odometer... one could think of a relatively convenient scheme where you can get your car inspected once a year at any refueling station, and tampering with the odometer is a crime. Won't stop everyone, but does it matter?

I don't think Odometers are reliable enough, especially as the basis for a tax. You'd certainly see an increase in average tyre size!

They're probably accurate to within less than 10%. How many kilometers would you have to drive to save a dollar from slightly bigger tyres?

I don't understand the opposition to this. These vehicles continue to use roads but don't pay any taxes that would help maintain roads if they were gas or diesel cars. How is that fair?

While maintaining pavement is not all of road maintenance, it is the central aspect. Trucks wear out roads orders of magnitude more than cars. In the US trucks pay much less than cars, in total, for road maintenance. It is likely the same in Australia. Simply rebalancing the taxation to the amount of road wear would eliminate the need to tax EV road use without it being a significant subsidy of EVs. Diesel trucks are…

Actually Diesel engines are the most efficient ICE in mass production, modern engines respecting the latest emission standards (ex: EURO 6) are some of the least dirty vehicles on the road. If you compare fuel efficiency per ton per kilometer and what is the pollution caused, they become quite clean. Yes, older Diesel trucks are dirty and also the ones with improper maintenance, but hitting at all trucks because of some is not fair.
