No, that means that the “terrible” AI won’t be longer an issue, as it’ll be more human, and how exactly do you think it’ll be “bad but not as bad as Forza 4 ?” do you even own or have played Forza 5 to base that argument ?. Seriously, quit trying to make it look like a gimmick, cause its not, its a innovating plus for gaming.

What they really mean is the terrible AI will kinda drive like a human but still be really bad but not quite as bad as it was in Forza 4. This is nothing more than a gimmick to get people to accept the fact they have to be online to play this game even while in single player mode.

No, didn’t you read? it means that, for example, your agent will learn as you play, to the point it’ll drive like you, and it’ll appear in your friend’s “world” as an opponent AI, so basically you’ll be competing against your friends every time (and vice versa).
