By the way, today's oildown penalty cost Morgan Lucas a top-ten finish for the season, by six points. He won the first round, but lost 15 points for an oildown. He would have finished ninth without the penalty.
Last night's oildown did not cost Tony Schumacher any points, he had enough clean-run points to avoid a penalty - which would have cost him the title.
The moral of this story is obvious.
