And there may well be more twists yet.
I think that it is simply a matter of circumstances, and what your view of "supporting" really is. I think that people feel that it entails far more than is reasonably practicable, whereas realistically, I think that in real terms, position swapping etc is rare outside Ferrari.
From my point of view, I believe that McLaren are far more likely to win the wc. Than Hamilton to win the wdc,so I would start by stating any decision that is made should not risk wcc points in any way. Secondly, a "do not attack" would be far less intrusive than a "let him pass" order.
Let's be honest here, how many times has the latter been an issue? I believe the former has been in play a few times however.
Also, as has been stated, it will depend on everything which is going on behind the scenes, which we do not see, for example, if Lewis has handed in his resi, and following the tweet, how disposed will the team feel to further his cause in the wdc by imposing team orders?
I personally think that team orders should not be used, nor will it make a difference, I do however expect a few races where not attacking is noticeable.
I also expect this debate to rumble on regardless of anything, with some thinking that Jenson should now start supporting Lewis title charge for next year, and some saying that Lewis should park sideways across the grid to give Jenson a headstart.
