So you are asking PD to turn GT7 into an arcade game. No thank you!
I'm not trying to be rude but I think GT7 is not the right game for you. GT7 aims to be realistic, and in real life, driving is not always easy and learning to drift requires a lot of practice. GT7 is not supposed to be easy, it's supposed to be realistic, and does it pretty well (although not perfect).
You need to understand that there are basically two types of driving games. Simulators and arcade (and games that fall in between these, but I try to keep this simple).
If you bought GT7, you bought a game that aims to be a simulator. If you buy GRID, you buy arcade. They are totally different kind of driving games and cannot be compared to each other at all. It's like comparing a nonfiction book to a fantasy book.
Simulators aim to be realistic and try to copy and simulate the real life laws of physics as accurately as possible.
Arcade games instead, are more like an artistic vision of what driving could be.
For some people, like me, the realism is equal to fun. The more realistic the driving game is, the more I enjoy playing it. If it feels too difficult for me, I will practice and try to become better at it.
And because I think realism = fun, games such as GRID, NFS, DiRT or Forza Horizon feel super boring to me. Driving in these games simply isn't fun and the way the cars behave make absolutely no sense to me. They behave nothing like cars do in real life.
And funny how you are saying that in GRID you feel like the car does exactly what you want, because that's exactly how I feel when I play GT7.
But when I play GRID, NFS, DiRT or Forza Horizon, I feel like the cars do not do what I want or expect, because the physics in those games simply does not work the way I expect physics to work.
