Maybe, but history isn't on its side. There used to be an 1/8th mile track around Tamiami, it's closed. There was a short track way back at the South Florida Fairgrounds, it closed in the 70's. Palm Beach International Raceway (Moroso) is slated to become an Amazon distribution center and there's some serious objection not only by the residents that will have to deal with the trucks, but Pitbull is the most vocal advocate for keeping the track.
Other than Nascar moving to Homestead, racing doesn't really appeal down here. Which is actually kind of interesting that Homestead didn't get the Grand Prix race.
