With 83 constructor points and 52 driver points gap respectively as well as 10 remaining GP's left, it is virtually impossible for McLaren to secure either driver or constructor championship. Hence, they should divert or focus more on next season championship. Furthermore, Brawn GP had shown no sign of deterioration in performance, therefore they are likely will collecting more points in comings GP's.
Lewis Hamilton has shown it remarkable performance in using a lousy car, thus it is undoubtedly proof of his worth. Now the ball is in McLaren court to turn it lousy car into a race winning car. Based on my observation from several past GP's, McLaren car clearly losing a aerodynamic grip for fast circuit, there only Monaco circuit where it need a mechanical grip in which McLaren had squandered by losing a valuable points there.
Compared to last season, there were slim margin between McLaren, Ferrari and BMW Sauber since the very first day, thus it had forced the championship to be decided right down to the wire.
