I wasn't trying to prohibit discussion. I asked a question that you haven't answered.
How do you propose total miles versus miles driven in different states should be resolved?
I don’t have a solution to that. Although technologically it’s a trivial question, it poses obvious privacy issues.
The issue applies today to some extent. I’ve lived a couple of places near a state line where the gas was always cheaper on the other side. So we always drove across the border to fill up.
