I'd start off with adjusting 1st gear. It's useless during a standing start. I, personally, set off in 2nd gear, TCS 0.
The car lends itself to cosmetic changes. Wonder if GR AUTO(not a typo) makes a debut in GT Sport.
#FakeNews - Toyota will never do that. I'm sure they'll use like 4 TRD (or Gazoo) nerds that like the game and that is all.
Considering Tetsuya Tada, Gazoo Racing's chief engineer, ask Kazunori Yamauchi for GT Sport players help, I'm not sure how that's fake news. It's about as direct of a source as you can get. Plus @Famine doesn't really have a habit of making things up.
Oh, and nevermind that the GTP team was actually in Paris and participated in a number of the events.
