I remember my first test in F1. After five laps, I came back to the pits and tried to play it cool - 'Oh yeah, I'm fine, I'm on top of this' - but I was completely lost.

It was an unbelievable experience! The brakes, the g-forces and the power of the engine are beyond description. Thanks to BMW and WilliamsF1 for giving me this chance to test. The test team looked after me brilliantly and I learnt plenty.

Driving at high speed where safe and legal is part of my life. As well as a higher top speed I wanted even better stability in my FX and that meant work on the aerodynamics.

There are some things that you can fulfil with money, but at the end of the day these are not the things that make you happy. It is the small things that make life good.

I don't care what other people think as long as I am happy. The day I die or retire, I have blown all my chances because I don't have the chance any more to change my image as an F1 driver.

The bottom line is what we do might not be the safest so there is always some risk but we are ready to take that into account because we love racing and we love motor sports and it is dangerous.
