I mean, I absolutely love the extra management aspects, but how the current game system works make infinitely more sense to have an Owner Driver than having to hire two non-user drivers.
Like, what's the point to hire two expensive driver if player can always have the advantage to overperform with a cheap one, by driving as them?
If incorperating Owner Driver back to MyTeam is too much too ask, simply having an "Add Custom Driver" to the driver market would strike-two-birds with-one-stone, by both solving the issue of the currently very dull driver market, and fulfilling the desire of player driving as themselves (even in a less perfect sense, it's still better than not)
The Custom Driver stats could be either freely editable, or can just make them work like in Driver Career, where it changes based on your performance (if you're driving as them)
