>The tax provision's original intent back in the 1970s was to enable small farmers and self-employed workers to buy a truck or van without having to fork over the luxury car tax that was then in effect and has since expired. At the time, it made perfect sense to qualify the vehicles by weight because no luxury cars exceeded the 6,000-pound gross vehicle weight threshold.

Obviously they didn't have any programmer aboard when they wrote that, back then. We already have a Pavlov's reflex to spot such mouse holes through which elephants pass later.

And the lawmakers always seem to believe into the illusion of them being an impartial observer, out there in the vacuum, as if the reality they are trying to influence will not change once they influence it. The simple (f)act of such a tax break being based on weight has caused the manufacturers to start making heavier luxury cars.
