I clipped a Ferrari, hit the gravel trap at a fair old speed, which lifted the car up into the barrier, and then rolled a few times. I had no injuries or anything - I just had to wait for the marshals to right the car before I could get out.

I have been waiting to win a world championship since 1985. I've had three cracks at a world title - in karting, I finished third at Le Mans; that hurt because it was very close, but then in Formula One there wasn't really an opportunity to finally crack it, so it's third time lucky.

The main factors in terms of how tiring a season can be are governed by the number of races and the length of time between the first and the last.

My very first car was a grey Alfa Romeo Alfasud, which I got in 1987. But, in our family, all cars were for sale - so they might be there in the morning and were gone at night. In the mid-90s, I joined Porsche and the Carrera was the car, and the Carrera 4S was the one they gave me. As a wee boy from Dumfries, I couldn't believe it.

What I like is when you can hear the heart and soul of music and can feel the energy coming out of it, because that's what it's like when you drive.

Especially with sports cars, when you have got so many cars on the track with various degrees of competitiveness, then something will happen. It's the nature of racing, the law of averages. If you want to be a front-runner then you are going to have to push very hard, and collisions can happen.

I try to get away from the pits as quickly as I can. I speak to my engineer when I get out of the car, usually there's some press to do, then I will go off and have a shower and get my dry, clean overalls and clothing on. I'll have a massage, stretch and something to eat. I don't sleep, but I try to close my eyes for a while.
