Oh my misunderstanding.
It's already looking like letting the teams dictate a return to an aero-dominant formula has just created a massive chasm between the front and back of the grid in Melbourne. Not that I have an issue with a gap, but the combination of aero changes plus wider and grippier tires is the fans will probably whine about this version of the racing saying overtaking is impossible. Actually Max Verstappen made not that he felt overtaking will be infrequent again. Then you're back to the same ........ of "this sucks" from the fanbase at large. The problem is, most of them haven't got a real clue as to what F1 races have been like historically since ground effects were banned after the 1982 season. The perceived parity that existed in Formula 1 hasn't existed for several generations of fans now. We're a long way from the days of Jimmy Clark running the Tasman Series down in your neck of the woods with non-winged cars.
It's why I sit on the fence about the banning of the winglets in GP because I hate to see ingenuity in design banned because it's aimed at hurting Ducati, yet knowing that F1's primary problem is aero-related, I don't want to see GP go down that sort of path no matter how innocuous it may seem to the fans. Once you go down that route, and then you start trying to do funny .... with the tires, that's when things go off the rails. Like you said Phillip Island 2013 may have been the test run for such fuckery, but it seems GP at least recognizes there's things from F1 to not mimic as it leads to the current product. So they've managed to keep GP looking like an interesting series by trying to clamp down on certain key technical areas for better or worse.
