In trying to simulate a bit Preakness with Original Circuit track design, I say yes. Yes, the chicane too.
Off the top of my head, Spa, Suzuka and Gilles Villeneuve have chicanes that slow the cars right down, before the run to the flag. The redesign of Trial Mountain suits that same type of run.
We already have Spa and Suzuka. This assumes “make fictional tracks function like real tracks = better” Why is that necessary for a fictional track with bare rock faces and cliffs? Must every track have a slow chicane before the finish because Spa does? Sounds very predictable and cookie cutter to me.
To me Trial Mountain was never meant to be a realistic track to emulate real life racing. It’s a video game, why not have some realistic tracks and some that are old school and a bit whimsical? If every track abides by these standards set by spa, how will Fiat 500s and Diahatsu Midgets feel? Lol
I think GT Sport opened up a huge can of worms. Now we have Gran Turismo fans who want everything to be balanced for e-sports and simulate real world racing. Along side long time fans of the franchise who have strong attachments to the way things were. Fans of the same IP who expect and want wildly different things. Pleasing everyone with GT7 might prove to be a huge task. Makes for interesting forum posts at least.
