Why?? Every car that still runs has an odometer (when was the odometer introduced?? Long, long ago certainly).
"If" said tax requires ANY "added electronics", then it proves itself to be a means for people tracking and NOT a tax.
All this needs is to designate a car-related business in your home town as your "reporting station" that you would stop by on a (say) monthly or quarterly basis to have the odometer reading recorded and sent in.
You should listen the the talk show people here in Seattle where the state government is talking about taxing cars per mile and a transponder is used to monitor your driving habits, where you go, how long it took you to get there (speeding much?) and that info goes direct to the state patrol.
