The team is bigger than the drivers, the drivers race for the team. McLaren can handle it how they want, but I think they're being stupid and are just not confident in being able to keep their drivers happy.
I don't really get what they are being stupid about.
There are plenty of races left and its not like Button is out of contention for the WDC even if most people believe he isn't a good driver, id agree if it goes down to the last race and Button ends up finishing 1 place ahead of Hamilton which costs Hamilton his WDC for example but when you have 2 cars that could win the WDC team orders shouldn't even be a consideration.
I'm not encouraging them to use it now, but hasn't Whitmarsh just said in your example that team orders wouldn't happen and he'd rather lose the WDC? He seems to be making an ideological statement that they will not happen at all (within Mclaren).
And as i said if the example i gave were to happen in Abu Dahbi i would agree with you that the team and drivers were stupid, but there are plenty of races left and neither driver really has the upper hand especially considering how the season has gone so far.
What happens if in 4 races time Mclaren decide to go with Hamilton to win the WDC and he finishes 1 place ahead of Button in Brasil but than crashes out in Abu Dhabi and Button looses the WDC by a couple of points which he would have had if he had finished ahead of Hamilton in Brasil? you would say that Mclaren were stupid to pick Hamilton over Button.
You cant predict the future even if 1 car is significantly faster for most of the season it doesn't mean he will be at the end aswell, so in my opinion using team orders to help 1 driver win by sacrificing the other is just silly and in most cases if you have 2 competent drivers letting them battle it out all the way gives you twice the chance of winning the WDC and a much higher chance of winning the WCC (unless you have Vettel).
If people want Team orders than teams should have a clear number one and number two driver system which as far as i know has never and hopefully never will happen.
