With regards to the myths of Oscar not being part of McLaren's podium championship celebrations and the radio scenario.
Firstly the podium celebration was hastly arranged by the FIA and at the last minute, secondly, it is a rule that other drivers go to the media post race interviews in the 'pen' after the race and during any podium celebrations. So Oscar had to be there as according to normal protocol.
With the radio, Oscar didn't hear anything from Zak because he'd already turned his radio off before entering park ferme, as is usual I believe.
So just media tattle tattle.
