I’m not certain I agree with the premise that mileage is a good indicator of road wear.

I do about 30k km in a typical year. My families live far, so a return trip is around 4000 km.

If we visit our family 3x/year, we’ve effectively exhausted this “10k mile” thing (I don’t live in the UK, but the point still stands), however very little of our actual mileage would be in our home country. To be precise, only 300km out of 2000.

If I go in other directions, the math gets even worse. I can leave the country in 30km and add 800-3000km of mileage for a scuba trip.

The amount of damage you do to the roads is exactly proportional to how many miles you drive on the roads. Where the roads are doesn't matter.

What you're describing is a billing detail - how do ensure the right chunk of those fees goes to the owners of those roads? And that leads to the conundrum I posed - without tracking your location at all times there's no way to prove what number of miles were in one municipality versus another.

It depends more on vehicle weight than miles driven

Yes, that was exactly my point. A local government handing me a bill that is not proportional to which roads I was driving on.

There are many systems, many of them imperfect. The vignette system, per week/month seems maybe the most responsible, as it guarantees I’m paying my due in the place of and proportional to the amount of time I will be using the roads.
