It's not about the second move at all, it's this rule that Rosberg could've been in contravention of:
Alonso was screaming about "leaving room" which indicated HE thought the rule was that he had to leave a car width to Rosbergs right. He don't, I think we all agree on that. Rosberg doesn't have to leave any space at all when making his first move.
Just to clarify a few things:
* Lewis was to a small amount alongside, at a late stage of the move.
* Alonso was NEVER alongside.
The stewards make this very clear, which indicates they have seen the relevant onboards (I hope). It's a factual statement, regardless of what a wide angle lens indicates from the front.
This means Alonso has absolutely NO ground for complaint. The only dodgy move is the one on Lewis, where I usually claim that if a car has even a small amount of overlap he has right to space, but it has been shown again and again that I'm pretty alone in this view. The rest of you usually don't agree (Button on Lewis in Canada, etc etc etc) and the stewards very rarely agree, so I have accepted that... In this case, the stewards say that the overlap happens so late and when Rosberg already is commited and can't possibly know Lewis is alongside. But it must have been borderline.
