For proof that NASCAR's "good ol' boy" racing ethic* is alive and well in other venues, we have BAR's recent bust for getting clever and then getting caught:

The BAR team has been banned for two races for running an underweight car at the San Marino Grand Prix.
...
FIA president Max Mosley said: "The facts in this case are very clear.

"The team was asked to pump the fuel out of their car [before checking it was above minimum weight]. They left 15 litres in the tank and told us it was empty."

F-1 is justifiably famous for its byzantine rules and a compliance policy based more on team popularity than on evenhanded judgement, so this is a little more gray than it would at first appear. Still, you'd think that with this arbitrary reputation the team would've thought better of trying to squeak by on a technicality. Bit them on the butt this time.

* "We don't break rules, we make rules." was (as I recall) Darryl Waltrip's quote about "cheating" in NASCAR. This is almost certainly what has happened here... when the spirit of the rules doesn't exactly square with what they say, clever people can wedge in advantages. At least until they get caught.
