I thought the officials did a really poor job (again) on the weekend at Sydney. Even if you put aside the fact that Winterbottom didn't get a penalty for tapping Lowndes into the barrier (dismissed by McConville with a wishy-washy answer that goes against precedence and veers towards "We wanted to keep it entertaining"), the fact that he didn't get a mechanical black flag despite the right rear window being dangerously unsecured was a complete joke. Additionally, Will Davison didn't get a pit lane penalty for refuelling the car off the jacks in race 36, despite it being shown in replay on TV and the commentators specifically mentioning it.
Anyway, second time Lowndes has been knocked out of a title fight by contact from another car. You could argue that even without the contact with Winterbottom he wouldn't have won the championship, but it would have been nice to see a fair fight.
