Which is more popular, Indy racing or NASCAR?

After delving into the world of motorsports, it seems that NASCAR holds the crown for popularity over Indy racing. This is largely due to its deep-rooted history, fan base and wider media coverage. NASCAR's appeal of high-speed, bumper-to-bumper racing offers an adrenaline rush that attracts viewers globally. However, IndyCar, with its unique style and high-speed open-wheel races, also has a dedicated following. While both have their merits, NASCAR's widespread recognition and fan enthusiasm seem to give it the edge in popularity.
