CART is one of the safest racing series in the world.

One thing I would like to see is a stronger ladder series for up-and-coming American drivers.

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.

And when we go from braking to accelerating to cornering, the G-forces we pull are really demanding on our bodies. We definitely have to be in top shape.

Believe me, you lose more than a gallon of fluids during a race. You could lose between six and 10 pounds during a race, depending on hot it is.

If CART continues on, it's just going to drag all of open-wheel racing down.

When you're in the back of the pack, you can gamble a little bit more.
