They'd be well aware of indy car - there was an Indycar event on the Gold Coast (in Australia) for a while (apparently up until 2008). As always with these things it's about licensing (and whether or not FM think they can see a return on their investment).

IIRC there have also been quite a few drivers from the Australian V8 series who have gone on to race in Indycar over the years - a quick google search says there are even current ones.
