If there's to be an FH5, can you add drivetrain matching in addition to PI matching when racing AIs?

PI matching means nothing if your drivetrain gets you worse performance compared to otherwise-similar vehicles in PI. I’m pretty sure the game derives its car configurations from tunes posted by other players and most of those people are driving AWD cars. RWDs get swallowed up and can never catch back up to the rest of the race because of their significantly weaker acceleration (they corner better but it’s not enough of a trade-off).
