In NASCAR, you don't have to be as physically strong as in some other forms of racing. You've just got to be able to endure the heat and endurance of it.
The trick at Le Mans is to get the car 'in the window.' Everything is critical: the tyre pressure, the brake temperature, and that means you have to push the car a lot to get it into the window - it's about getting everything to work right and getting the car to flow through the corners.
I'm not like other females. I'm obviously different because of the path I've taken. I'm just as aggressive as the guys when I get my helmet on. Plus F1 is not just about taking risks, but knowing when to take risks and when to back off. It's also about strategy and managing your tyres.
When I got to Ferrari I learnt to be less aggressive, and how to set up the car for my driving style.
When I entered Formula One in 2002 basically all I had was my talent, but now I also have the technical knowledge which enables me, together with my engineers, to fully exploit the potential of the car.
Formula 1 is such a big jump from Formula 2, and there are so many new things that you need to learn.
Things can change very quickly in Formula 1.
In sport there is never any moment that is the same as the other. I have been in Formula One for 12 years, and out of that I had one year with the perfect car.
Preparation for Monaco is a little different: you definitely build up a little bit slower throughout the weekend and pace yourself. It's important to find the limit carefully.
As soon as you go off the racing line you go through all the dust and then have to spend time cleaning up your tires.
The Pirellis you can push for a couple of laps and then you've got to start saving. It's not easy.
There's no better benefit than being out on the racetrack, learning what's going on with the track and the tire and all that stuff. To me, that's a big influence.
We have moved away from basic racing, where you see how the drivers fight with the cars to their physical limits and then make mistakes - or not.
I think people - especially folks who haven't seen a lot of NASCAR - they get this idea that we're just going around in circles. And that's so far from the truth. You're running as hard as you can to get all you can every lap.
You've got to distribute the tyre life over the stint, I think that's the main limiting factor, more than car balance.
You never want to concede a place, but when you're leading the race or fighting for a podium position, you can find ways to make your car very wide!
Running on different types of racetracks is challenging - not only for the drivers, but even more for the team members who have to make adjustments to the cars before each race.
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.
The key is trying to go quick without killing your tyres.
Mile tracks put more emphasis on the driver. On the longer tracks, you can drive flat out all the way around, so it's more of an engineering exercise. On a mile, you can't run flat out. You're constantly in traffic, there's more driver involvement.
