soon it may/will/possibly be any number of makes....and it will stay that way until this green battery rubbish idea gains enough popularity to take over.......
Firstly it's great to be able to have this discussion here, it's probably happening on various other boards as well.
My point is that there will be change and with it will come some anxiety. I think if your a realist, then you can see Supercars in its current and proposed form [Gen 3], changing to be something different. What I suggest, TCR's, is one of the options, because it's already here and supported by many here, including the likes of Garry Rodgers, someone well respected in motor sport, as well as others mentioned in this discussion.
Yes, I can see the "Green Battery Rubbish" becoming the norm, because no matter what it is, people, boats, horses, dogs, cars and anything else you want to add, have been raced. That's what "automobiles" will become and we'll see them burn rubber up Mt Panorama with a magnificent "whir" [Cue Formula E car accelerating - https://www.youtube.com/watch?v=wiLWVuI4f0A]
As much as many might not like it, due to the fact that we don't manufacture cars in Australia, our cars will be built overseas, and some will be cars that are developed to be raced world wide. If they're "Mum Cars" and you don't like that, support something else like AFL/WAFL!. ["That's something that doesn't change with the times" he said facetiously!]
PS - Go Sainters, at least we supporters know how we will go, holding up the rest of the competition!
