I have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent money.

I'm world champion, baby!

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.

It doesn't matter who wins if I don't. I only care if I win. I'm jealous of anyone else who wins.

I love cycling, running and swimming. In recent years I've competed regularly in triathlons, which means I don't find the physical side of driving a struggle any more.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 320km/h, the noise and the vibrations are incredible. The G-force when you take big corners is like someone trying to rip your head off. You hit the brakes, and it feels as if the skin is being pulled off your body.

We all drive differently and have different styles. For me I need a car I can develop beneath me and feel comfortable in. If the car feels neutral and unbalanced it doesn't work for me.
