Pretty much everything in 2011. There are die-hard Hamilton fans who deny that anything was wrong last year, and that everything was the team's fault. They still insist that Lord Lewis was on top of his game last year, and hold it against McLaren. They are the people I am talking about, who would have started these rumours because Hamilton moving to a team like Lotus and succeeding would prove that it was all McLaren's fault.
what has he done wrong in the car?
Perhaps the more-challenging question is what Hamilton has done wrong
out of the car. And the answer is that he has shown some of the most erratic, questonable and bizarre behaviours from a driver that the sport has ever seen. Posting the telemetry on Twitter is just the tip of the iceberg how about his infamous dont touch me, man! episode in Singapore last year? Or his Bob Marley helmet in India, which was meant to represent no woman, no cry and his on-again, off-again relationship with Nicole Scherzinger?
For the time being, McLaren have tolerated it, though one suspects that their patience must be wearing thin by now, and its not beyond the realm of possibility that the only reason why they havent let him go yet is that they feel any other driver is going to be a step down from him, but sooner or later, he is going to stop being an asset and start being a liability, and when that happens, McLaren will walk away.
If that happens, teams like Lotus and Ferrari and Red Bull aren't going to be interested in him.
Mclaren are probably the worst team on the grid at turning performance into points.
