He took the old wing because it felt better andhe was advised by the team that the difference was minimal and the old one would be faster in quali.
Fart useless piece of advise that was!
You can not blame the team for that; Lewis made the ultimate decision; how many times has Jenson gone against the team, with varying levels of success, the driver has to take responsibility!
Okay... here's what I've got to say about that. Because you can't have it both ways. So it's Lewis fault when the decision to put on a wing that ultimately is not as good. Fine, I get that the driver bears ultimate responsibility, even if his job is to drive. The engineers scrutinize the data and in the end I think it was just a poor decision on the part of everyone. No harm done, McLaren today had the fastest car by a country mile.
So what's the hubub bub? Well, when Button spent half a season blaming the car for its no grip woes, its massive understeer and its lack of pace while his team mate was five or ten spots up the grid whose fault was it then? You know you can't have it both ways.
Strictly speaking from a McLaren fan point of view, and taking off your Button fan button... you know today's result was a gift for having made the right call. No need to defend it no need to attack it. I hope he goes on and takes the win if he can.
