My first Indy 500 was one of my high points. I ended up qualifying fourth and I finished fourth. I had a win in Japan a few years later, and then qualifying for Daytona was great as well.

I want to win at everything. I usually don't like things that I'm not good at, but it doesn't mean I don't want to win at them.

I've read stories that are set in a celebrity's house, and you know where it is and what it looks like and what's inside it, and that's not something I want anyone to know.

I feel like with Indy cars, you can just show up - if you are equipped to build and make a nice car, then you could be competitive. But in NASCAR I don't see that even being possible for someone to just show up with a car. There's too much evolution of the tricks and bells and whistles and all the things it takes to be fast in stock-car racing that you wouldn't know.

It would be hypocritical of me to use being female in some ways, and diss being female in other ways. It's part of the programme.

I've never been bashful to say that I'm not really interested in Formula One. When I lived in England, it's all I wanted to do and I thought that anything else would somehow be a compromise to my dreams. But then when I came back to the States, I realised how much I loved being back in the States...

You have responsibilities and if you want to be the best in your industry you need to have a relentless dedication to your job. I was fortunate to have support from my parents and sister growing up and that helped me a lot.
