America's Army the original one ended up being a terrible game for playability, because it turns out making rifle shooting even semi-realistic is hella boring lol.
Lot of slowly crawling around the map on your belly, calling positions to snipers and grenadiers, and just waiting.
I haven't looked at it in decade++ though, so maybe it's an actual game now.
I don't think AA was ever legitimately meant to find people in that way and was just a more traditional advertisement/propaganda tool meant to feed anyone into the recruiting pipeline.
Ok I looked up the more recent version of the game, apparently it has in fact capitulated to populism and no longer emphasizes realistic tactics. Supposedly many servers will kick you for camping now.
I thought perhaps you could substitute AI driving when the human does something egregious, but realistically it should work the other way around. AI can handle the rudimentary stuff, it's the extracurricular road situations you will want the human in charge for.
I don't think that will work. Either you need to have the players legally liable for any damage and injury they cause, or you have created a platform for motivated psychopaths and terrorists to kill people with impunity.
I know, I just don't think that's feasible. The outcome would be some people figuring it out, and having legal cover to commit murder since they were just playing a game. Cue long legal battle over culpability.
I would be curious if these simulations can be made accurate enough to filter out candidates for driving. Set up a series of scenarios and grade how each driver performs. Then long term compare that to actually perform if hired.
Building off another comment, enough drivers could be used to help train an AI how to drive or how to reach specific situations.
