I liked F1 here, never missed one. Cheap tickets, 3 hour drive from home. The locals are great, warm, friendly. Since F1 been going to 500 mile race. Lately they have been good. And the Brickyard is the bomb. It really is the temple of (USA) racing on so many levels - the vastness of it thrilling to the eye and the ear thanks to the steel grandstands.
Indycars are not F1 bit I say they are pretty good racing recently. And they are cheap - cheap cars, cheap (owned, not used often) track, cheap race tickets. Who cares if nobody comes, nobody will still be 100,000 tickets... Maybe some watched "Rush" and these guys race the same cars ( ); more importantly a lot of passionate but broke racing fans will show up.
AJ criticism would be right if Indy series was what it was when I grew up and he was winning. They have to get relevant today, and be ready to be relevant tomorrow, when kids ride around in self-driving cars streamed from Google. This is a good move. I'm in!
