Where was that stated,that when they are on different strategies they don't interfere with each other ?Who told you about "The Clear Strategy" ? Paddy told Lewis to let Nico past,at no time did Lewis refuse to let him past at that point in the race .Lewis said "When he is near enough he can come past" But Nico was never near enough to take that advantage so really in that part of the race Nico was not held up .When Nico pitted and came out with new tyres,it was then a race to the finish ,and at this point there were NO team orders or requests to Lewis,and he defended his position to the end of the race as any RACING driver would have done in his position.
Nico,s problem seemed to be with Charlie bringing the safety car out ,in Nico,s eyes at the wrong time .But Charlie can see all the race on cameras where as Nico only see,s what's happening around him !
