Open up every event to every car. Have all Autolog leaderboards be car-specific, rather than event specific, even the open world challenges, such as billboards.
I've depleted my Autolog of challenges, and my friendslist is all filled up. Guess I'll have to kick some people and look for active players at level-cap, to get my compulsive asymmetric Most Wanted highscore chasing on.
Really irks me, how much more Autolog could offer, with this simple tweak. Wonder why EA/Criterion kept its appeal artificially limited. Shame.
