I played NFS Shift 2 that allows us to have 2 types of tuning, dumbed down and advanced mode.
Basically the dumbed down mode just gave us some kind of slider such as:
Short ========== Long
Understeer =========== Oversteer
But when you go to advanced mode, you will see that the simplified gearing is tied and alters final drive, individual gear ratio, etc. Handling setting alters tyre pressure, tyre balance, camber and other suspension settings, etc.
It can be a solution to satisfy both newcomers and advanced players, but won’t satisfy devs in terms of work that has to be done though
