So you are agreed that favouritism happens at McLaren!! RESULT!!
I agree that EQUAL is impossible. But reasonably equal is totally possible, and its the most common approach... until something more important comes forward, and then the team people make decisions, normally towards the interests of the team (in whichever form it may come). It's their decisions to make... so to each their own. Scissors beat paper... it doesnt matter if paper is nice.
In the case of Mclaren, they are "reasonably" equal. Even though Ron always expressed his favouritism towards some drivers it didnt go too far... during the Whitmarsh era, things are a bit more equal; Whitmarsh has a position to defend and is very pragmatic in his approach... Perhaps its in his nature to be pragmatic; but he aint no team owner, so we can't say for sure.
To say right now that Mclaren are favouring either driver is pretty blind. Because truly... they have absolutely no reason to. If this case was true (ie the conspiracy theories were real)... people should get fired.
Came out fighting indeed.
