'miles driven' tax

[True Federalist (진정한 연방 주의자)]

We do need to consider what will replace the fuel tax as a funding source for roads when we transition to a post-internal combustion society.  However, there is no indication that will be happening soon.

Terrible idea. You'd need a new layer of bureaucracy to implement it

Not really, not if it's used to fund local roads and a cap is established on how many miles are taxed.  Most, if not all states require you to pay property tax on cars and the county sends you a bill based on the blue-book value for having been driven so many miles (in SC it's 15000 mi/yr) with a way for you to appeal the bill if you've driven it more than that so that it has a lower value.  Set the tax based on the assumption you drive the vehicle 10000 mi/yr and let people appeal it if they can show they drove less.  Other than you'd get more appeals thus making that layer of the bureaucracy bigger to manage the increased workload, there would be no real problems.

As a replacement for the federal gas tax this wouldn't work, but for state and local gas taxes it would.

Wouldn't that defeat the entire purpose the tax is being proposed for considering that it wouldn't tax the people who drove more than that anything additional?

I'll agree that it is opposite to Mitty's proposal, but as an anti-greenhouse gas measure, either the existing motor vehicle fuel taxes or carbon taxes are simpler and more directly relevant to the alleged goal.  I was considering whether a miles driven tax could be used as a substitute for fuel taxes as a means of paying for roads once we all have vehicles powered by batteries and/or hydrogen fuel cells.

Same basic concept, but far different reason for implementing it.
