I foresee a mileage usage tax on ALL vehicles. Personally I think this is a precursor to just that.
It won't be long before every internet transaction will be taxed.
It seems to me the government looks to tax and charge everything they can. Hell, I pay $6.00 a year just to permit my 7 pound poodle.
I get charged $14.00 for a state worker to tell me my "check engine" light is off and my car must be running clean emission as a result of the light being off.
