Tony Stewart was about to run his first Indy 500. It should have been the best day of his life.. but he was the only star who showed up. That fateful day is now known in racing lore as part of “The Split.” But how did open-wheel racing get to that point? What exactly is the difference between CART and IndyCar and Champ Car and all the other names we call this sport? And why does it always seem to be in turmoil? Today on Past Gas, it’s a brief history of the many dramatic twists and turns in the world of IndyCar.
