Hamilton has been known to wear his heart on his sleeve and speak his mind. However, there was more than one occasion in 2013 when he lost his cool.
Having qualified a season-low 12th in Italy, Hamilton said he “drove like an idiot” in his post-session interview.
More was to follow in the U.S., when he delivered some rather bizarre mixed messages to his team via the radio.
At first, when told to look after his tyres, he told them to “let him focus.” Later, he criticised them for not giving him enough feedback.
As quoted in the Guardian, Hamilton barked: "You need to give me some feedback, man, tyres, temperatures."
Team boss Ross Brawn was quick to play down the issue, but clearly this is one aspect of Hamilton’s persona that still needs working on.
We are just getting used to working with Lewis. I am sure there are different levels of frustration with him. The first level, you just wade through. It's part of building a relationship. It's not problematic.
In contrast, Rosberg was the personification of calm. Even on the three occasions he failed to finish, the German was always pragmatic as to why it happened and never let emotions get the better of him.
Therefore, even though Hamilton edged the points battle in 2013, it could be argued that Rosberg was the more rounded and consistent driver overall. It certainly gives food for thought for 2014.
