Helio: NASCAR is the biggest

IRL driver Helio Castroneves admits NASCAR is the biggest and most attractive racing series in America. How could it not be after Anton George created the IRL, split open wheel racing in America, and destroyed it.

"I think, definitely, NASCAR is the biggest motorsports series in America," Castroneves said. "The popularity is huge. Drivers want to go and you want to take the challenge. Obviously, I'm dancing instead of going to NASCAR — it's a different challenge.

"I enjoy open-wheel racing, but if I have an opportunity to try something new and different, why not? [Dario] Franchitti accomplished his goals [winning the Indianapolis 500 and IndyCar Series title this year], so it's natural. When you see something that's similar to what you do, you want to try and see what you can do."
