WhiteBlue your biggest problem is that you are doing exactly what you accuse others of doing and inventing rules.
The two rules you think NK breached are as follows:
20.5) As soon as a car is caught by another car which is about to lap it during the race the driver must allow the faster driver past at the first available opportunity. If the driver who has been caught does not allow the faster driver past, waved blue flags will be shown to indicate that he must allow the following driver to overtake.
16.1) Incident" means any occurrence or series of occurrences involving one or more drivers, or any
action by any driver, which is reported to the stewards by the race director (or noted by the
stewards and subsequently investigated) which :
16.1.d) Caused a collision
From those rules you then go on to assert:
WhiteBlue wrote: The whole sequence of events up to the point where NK and SV were side by side is is largely irrelevant to the incident because SV had the right to maximise his pace and optimise his racing line.
The rules do not say that. How on earth do you get from "must allow the faster driver to pass at the earliest possibility" to "has the right to maximise his pace and optimise his racing line"? The reason I keep asking you to quote rules is because you have quoted a couple of rules and then made all kinds of assertions about them like this one that simply are not true.
You can't just state things like this and have it accepted as fact if you repeat it over and over.
In my humble opinion the fact that Vettel had a speed differential and 15+ metres of track to play with was enough to ensure NK complied with 20.5. He let Vettel pass, he didn't try and block him. But that wasn't enough for SV. He took an unnecessary risk in going past NK more closely than he needed to and by not turning to follow the racing line but instead going straight and requiring NK to do the same.
Finally you state:
WhiteBlue wrote:I have pointed out the reason why the three corner rule is not applicable - because the duty to let pass ASAP is unconditional with regard to a collision. The three corner rule only applies to denying a legitimate pass, (§16.1.g&f) which wasn't the case here.
So you believe that if NK had swept to the right earlier and blocked Vettel from overtaking for a further three corners that this would have been fine and acceptable according to the rules?
The underlined passage is also your interpretation of the rules and not written fact.
Is this why you believe NK is at fault for Button losing control of his car and sliding into him?
I don't think much of the world is going to agree with you on that one...
