The better words here might be what affected the lack of action, because Sunday’s race, typical Indy fare, had far less of that than many events this year. And while tires and cars play a role, the fact that Indy itself is a big, flat track is what hurts the action the most. A racetrack can have all the history and prestige in the world for one type of racing, but that doesn’t make it an important place for everyone to race. Indy was built as a test track, and for Indy cars, it’s an ideal venue… but not for stock cars.
