>"Annoying but actually reasonable"
It is absolutely reasonable in concept. But it might not be in practice. I have zero problem with paying for my actual EV mileage in some tax. My State decided it was going to collect it annually during registration renewal. Also reasonable. But they either charge an "average" mileage of ALL EV drivers (however they determine that), or force me to put an always-on tracking device in my car. And neither is reasonable. And my vehicle manual actually says that such devices should not be used/left in the OBD port.
My State already requires annual inspections. AND THE ODOMETER READING IS COLLECTED at each inspection and entered into a State Police system by the inspector for every vehicle. So they ALREADY KNOW my mileage. Their "average" is an order of magnitude more than I drive.
I Emailed and asked why I am going to be unfairly taxed for way, way, way more mileage than I drive when the data is right there, already being collected by the State. And I refuse to be tracked with a spyware device that sends location and behavior data. The response was "well, we don't have access to that data, it is on a different State system". OMG.
So a concept can be fair and reasonable in many ways, and then be totally unreasonable depending on how it is implemented.
