How would they handle someone from out of state? If this applied in California, what would happen to an Arizona driver passing through the State?
The attendant would probably have an override switch that would cause the pump to revert to a per gallon tax.
In fact, that might be how they would get people to go along with this: raise the gas tax exhorbitantly, like say $1.50 per gallon, with the milage based system as a "voluntary" alternative. That way they could get out of the state paying for retrofitting older vehicles and the privacy complaints, saying that the consumer voluntarily bought the electronics to save on the tax.
Not sure.
I thought I heard that it was part of the computer system. IE: Your vehicle would keep the information everytime it was fueled.
Listen ... I don't think the public, as gullible as they are, will allow this. Some states? Perhaps, but with only (only?!) 30% of the population complete lunatics, fearing global warming, vanishing horny toads and whatever, I don't see this going anywhere soon.
Hell, the Dimocrats are openly trying to screw the young people by poisoning them (and seinors not even effected by it) against the S/S fix, so I don't see them (young people) supporting this kind of money grab.
