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.
The only time I think about life beyond F1 is when I contemplate becoming a dad. But there's no way that's going to happen while I'm still racing. To be successful in F1 you need to be very selfish in lots of ways and you're away from home for long periods. That's not the kind of father I want to be.
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.
