Why has IndyCar never gone global like Formula 1?

In my exploration of why IndyCar has not achieved global recognition like Formula 1, several factors emerge. Firstly, IndyCar is predominantly focused on American circuits, with a unique blend of oval, road, and street courses that don't appeal to international audiences as much. Second, Formula 1's aggressive marketing and branding strategies have given it a significant edge and international appeal. Furthermore, the technical differences and regulations between the two make IndyCar less appealing to global viewers who prefer the technology-driven nature of Formula 1. Lastly, the level of competition and the iconic status of Formula 1 teams and drivers has also contributed to its global dominance over IndyCar.
