Yes.
Even as a video game, it's mimicking real life. May as well have all generic cars like NASCAR, than try to mimic GT racing.
The point is, we know PD won't get it right. As you mentioned, it's a fact, after 3 years. It's not going to happen. However, it's not BS if I signed with Ford or Mazda and my car is crap. That's my choice. Others ain't going to sign with those brands because, more often than not, they won't be competitive. Is that any player's fault for choosing inferior brands? No. PD say choose your favourite manufacturer and race.
Maybe people should stop choosing the METAs. That's not a solution. Players choose what they think will be competitive. Via leaderboards or whatever feels the best to them.
Are PD going to stop using AI, to determine lap times, penalties and adjusting BOP, in Gran Turismo Sport? I don't know.
Well, the last BOP, I thought the GR.4 GT-R was worse. I put the thing on pole position. Except for my one red bar, I would have won the race.
If some player's cars are worse and some player's cars improved in the next two Manu races, then we'll know if the BOP balanced the grids.
