Hamilton's performances have been getting increasingly painful to watch. He reminds me (a little) of Damon Hill in 1999 - still able to put in a good showing occasionally, but his heart doesn't seem to be in it.
That being said, he is still 6th in the WDC, and ahead of the driver who took his seat at Mercedes... However, this says more about the performance gap between the top 4 teams, and the rest...
