Inconstancy throughout. Seems as if there maybe some history with a particular steward though.

What about KR turning his wheel in...would have been a collision had MV not moved over, pushing all the wheels over the white line.

I think this sums it up well:
Mercedes’ Niki Lauda waded into the debate by saying: ”They shouldn't intervene in situations like that. It was a normal overtaking move. You can't be more stupid than that."
