An engineer can look at the data, but he needs a translator from the cockpit - the driver - to understand it completely. For example, only the driver can tell you why he abruptly takes his foot off the gas pedal at a certain point. The data doesn't necessarily tell the engineer whether the driver made a mistake at that point or the car was acting up. The information the driver provides often helps determine the direction of development.

Losing composure is pointless.

Psychologically speaking, it's very important to be in good shape. I work in a sport that requires you to react quickly and be in excellent shape. Besides, things don't get easier as you get older.

With this type of thing there are always different opinions and mine is that it is impossible to blame either one of us. [on a crash with Heidfeld]

I have really enjoyed my time at Ferrari, not just because of the successes.

Technology has certainly reduced performance differences among drivers. Whereas a talented driver could get a half-second out of every lap in the past, nowadays talent makes up for only about one or two tenths of a second. But the driver is still the key factor.
