My brother was told that he wouldn't walk, that he wouldn't be able to play drums, that he wouldn't be able to race a car - and he's done all those things. He's defied the odds, defied disability. I look at him and I'm so inspired, by his mentality and by how incredible the body and the mind are. There's really nothing you can't do. My brother has proved that.

I love it in the States. The roads are big, the food is big. If it was possible to be in L.A. and still live my racing life, I would move now.

In racing there are always things you can learn, every single day. There is always space for improvement, and I think that applies to everything in life.

Nothing can really prepare you for when you get in the Formula One car. Knowing that you're driving a multimillion-dollar car, and if you crash it it's going to cost a lot of money, and they might not give you another chance, is scary.

I grew up going to the store, seeing the products [of L'Oréal ], seeing the commercials and the ambassadors. I never in a million years thought I'd be associated with them.

When you're driving, the helmet squashes your hair, so you don't really have a hairstyle. When you get out, you're sweating and your hair is a mess.

I can't go to the cinema. I go to the bathroom in a petrol station and people come in there for autographs. It's tough but I knew that was going to be the case.
