The main factors in terms of how tiring a season can be are governed by the number of races and the length of time between the first and the last.

It is hard to be number one, and it is even harder to stay there because everyone is trying to knock you off the top.

My motto is to do everything absolutely flat out and to the best of your ability.

I clipped a Ferrari, hit the gravel trap at a fair old speed, which lifted the car up into the barrier, and then rolled a few times. I had no injuries or anything - I just had to wait for the marshals to right the car before I could get out.

As a driver you enjoy winning races and, if you win in the easiest way possible, fine, but in reality we all remember the fights to the end, the nip-and-tuck stuff.

I don't do much driving - about 5,000-6,000 miles a year. And most of that is to the airport and to the racing circuits.

I think music can really affect people's emotions and, when I am about to get into a race car, I definitely listen to music with a good beat - that's when you've got the adrenalin pumping. And the time before you go into a race weekend, you have a lot of emotion and adrenalin, and a lot of focus.
