Huh?
F1's claim to fame is tons of money to fund endlessly high-tech cars, which often doesn't result in close competition. At least there is still a question as to which McLaren driver will win the championship. Or claim it after the other one folds. You can guess which one.
IndyCar was racing in California, where a certain Spaniard continued to wipe the floor with the other competitors. An anomalous season, in a spec series which is usually much more competitive. McLaren did finish second, and fourth.
NASCAR was racing at Indy, so there was that.
