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.

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.

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.

As a driver you enjoy winning races and, if you win in the easiest way possible, fine, but in reality we all remember the fights to the end, the nip-and-tuck stuff.

I think music can really affect people's emotions and, when I am about to get into a race car, I definitely listen to music with a good beat - that's when you've got the adrenalin pumping. And the time before you go into a race weekend, you have a lot of emotion and adrenalin, and a lot of focus.

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.

It was not until I started racing for car manufacturers that I found a car I could really get attached to. I am the son of a car dealer, so up until then, cars just came and went.
