“How do they propose to measure mileage use per year? GPS trackers in all license plates?”

License plates are renewed every year. Every 2 years in some states. Probably an odometer exam & taxes due on the license renewal date.

They would tax sex if they could find a way. Of course, same sex would be tax exempt.

They could mandate an on-board tracking device which is connected to Internet. For remote locations, they can use a satellite link. Mileage information could be sent intermittently.

I learned about two weeks after I got my license how to unplug the odometer.
