I've got Asperger's syndrome and I'm not a very good people person, so I've always been more comfortable around machinery. Not in a weird way - I don't want to marry my car or anything stupid like that!

I'm not good at happy, lightweight kind of music. I'm not really good at pop music. "Cars" is probably the only true pop song I ever wrote. I wish I could write more, but I'm not very good at it.

Strangely enough, when the Sugababes' 'Freak Like Me' went to number 1, which was built around my 'Are 'Friends' Electric' song, I had another song called 'Rip' go to number 1 in the Kerrang TV chart, so I was pulling new people in from very different areas of musical interest. That was quite an amazing week.

I have one brother, John, an airline pilot, who is seven years younger. He's adopted, though we're still blood related - he's my cousin. My parents couldn't have any more children after me, so when Dad's brother died, they adopted John, then just a baby.

When I was a kid it was big news when someone flew around the world in a little aeroplane, but nobody cared when I did it. Then, to rub salt into my wounds, the customs people ripped my aeroplane to pieces, looking for stuff.

Here in my car, I feel safest of all, I can lock all the doors.

I'm very intolerant and I get fed up with people easily.
