Doing the new K-Cup race makes me have to question: Why on earth is this kind of racing completely missing from Sport Mode?
They're super fun to throw around at 400PP, you can race them quite easily, it's a unique sector no other game touches, it's super on-brand for the series. It solves the track repeating issue, because you can actually use tracks like Eiger and the short Maggiore layouts at this size of car. I'm not saying open tuning, I get that open tuning doesn't work for the GT online audience, but provide two or three 400PP tunes for each kei car and run a race in them every couple of months or so, it'd be super fun.
