If I'd a wanted to pay mileage I would be renting.
I thought we paid taxes for mileage on our cars through the gasoline tax.
Expect these schemes to pop up here and there as governments deal with the disappearing white middle class, a source of property, income, and sales taxes. The focus is shifting to taxing the money passed down to their (often) childless children, who opt out of many (if not all) sources of taxation (home ownership, working, etc.). Taxing the “replacement Americans” (the foreigners trafficked here to replace the lost/non-existent generations of Americans) only goes so far; many of them also have no interest in contributing anything - yet they have voracious appetites for public services/benefits.
