So what would have happened if one of the non-points-scoring cars would have taken one of the points-scoring cars out of the race?

Being  mischievous for a moment, if I had been a Michelin-team principal, I would have thought that if neither of the Ferraris made it beyond 75% of the race, my position in the championships would probably be better. Not to imply that any deliberate accidents really would have happened, but think of the suspicion that would have made the rounds if an accident actually had happened.
