I don't think it matters if it was driven off road. With the way the current system works, the gas pump doesn't know how many gallons are being burned off regulated highways or how much of it is going into your lawn tractor, boat, ATV etc, instead it all goes to the same road fund. Would it really be worse to just use the odometer and bill every mile? I know i would pay the few cents extra for the off road time and have privacy and less tax on the gas not used on roads than to pay a bit less and be followed everywhere.
