Ok so the "answers" to the simple question in the OP are:
*If you've played GT before then you should know it's no more or less challenging than
any other racing game. (complete and utter hogwash)
*Quit taking max PP cars into the races. (which you've clearly stated you are doing just the opposite)
*Go online.
*Set a fast time in a Time Trial.
*This is another whining thread, move along everyone.
*Get off the forum, and go online.
*Go play iRacing.
*It is not up to the game to challenge you, it is up to you to challenge the game. (

that is an all-timer right there.)
*The only real challenge with racing games is online. (have these guys ever played any other racing titles?)
*This is an "elitist" rant.
*Join the WRS (online) then we'll see just how good you are. (so helpful, huh?)
*The game overall is tailored toward the "masses". (With no difficulty settings like every other "game for the masses", but we won't mention that.)
*Career mode is merely an appetizer, and nothing more. (wow)
*The challenge begins when the game ends..
*Start doing Time Trials
*Join a Race Series (online) and race humans rather than
AI that, no matter how fast it can go, presents no real competition. (Are these guys even reading the amazing, mind-melting statements which they type?)
*Even if they make a super fast ai people will complain because it's unrealistic, unfair, impossible to beat, or something like that. :eyeroll:
*No ai can offer a real challenge. They could(?) make perfect Vettel ai, but thats probably a waste of time in PD's minds.
*There is no way to make the AI "challenging" without hating the game.

*Online is where challenges are. Plain and simple. (yeah, there is something simple going on here, alright)
*I just don't think there is any way the developers can program the AI to match the full spectrum of player's skills from
beginner to
pro-level. (you mean like difficulty settings which are usually named exactly like that?)
*There's
no way to make the AI to be perfectly competitive for all the players. (not with one global setting, of course not!)
*Difficulty setting is also useless. (holy ba-jeebers)
*"I too am breezing through all those, but you don't see me complaining about it. It is what it is, just deal with it and play on."
Oh my lord, I must apologize to you jimbo11, for this poor treatment by the members of this forum. I hope that you stick around, as there are many of us who wish to see this racing game live up to its billing, including the marketing trailers that show... umm... races. And we will bring these matters up in a public forum, as I believe this to be our right and duty as GT fans. Some of you clowns are the reason that this game is perpetually behind, in so many ways..
