Because I am
...but seriously, after playing this game since it's inception, having a cornerstone of the game become a back burner feature irks me.
But I quoted you because you made a comment about "other pro drivers" so I responded. Also, the forum has a hard rule over multiple posts, so I put it all into one.
Back on topic, I see a huge conflict of game features.
The cars are setup with tuning in mind. As noted, some have an atrocious stock setup, probably because of the (largely) blanket settings. Everything has 7/4 anti-roll bars for instance. They really need to have some tune applied to them to be competitive outside of the single player game. If all you play is single player, then the game is designed to never need a tune. I would go so far as to say that the single player is a better experience without tuning.
But we're not talking single player here.
To have the raison d'etre of the game, aka Sport Mode, to be devoid of tuning seems super strange to me. It's supposed to be serious racing, with FIA sanctioning and ranking. The wins and losses mean something. Your behaviour means something. Isn't single player the "user friendly" part of the game? No PS+ needed for that. For Sport, I need to pay $70 a year. Yet, in this more serious mode, for which I am paying an annual fee to take part in, they choose to make it more user friendly. Seems backwards to me.
For 20 years, getting the best of yourself and the car has been about practice AND the tune to suit you. Essentially Man and Machine. Tune the man through practice, tune the machine through trial and error (or copying someone else's trial and error).
