I haven't got the yacht any more. The cost of running it was crazy. But it was so much fun while I had it. I don't regret it.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 200mph, 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.

We go through the whole season working on next season's car and developing the car and making sure we fit in the car and all that sort of stuff. And we obviously give ideas of what we would hope next year's car would have even if it's small things like buttons on the steering wheel and different positions and whatever.

When it comes to my racing career I'm very driven and very selfish. People who are around me at races will know that I'm a different person here than in my personal life. I completely blank people at races. I need to be focused. I'm rude.
