Perhaps they've invested all their shark card profits into an AI so smart, so advanced... what am I saying of course they haven't.
Also on a different subject, I would like a game to not 'wait for the protagonist' for events to happen. In Skyrim the world was frozen until you entered the scene, I can just imagine the people of Solitude standing around for weeks by the front gate to execute Roggvir waiting for the dragonborn to show up, muttering "he/she'll be here soon" to each other. I know R* handles such events differently to Bethesda and R* games are a lot less buggy in that regard, but I think part of a believable world is one that does not revolve around the protagonist. It's a difficult thing to balance, you don't want a player to potentially miss important story events and at the same time you don't want a situation where for example "oh don't worry this wagon full of bullion will hang around in town for as long as it takes, even if you spend weeks getting here because you're picking flowers and hunting deer."
Finally I hope the fucking railway makes more sense this time, in the first Redemption it was ok and had an actual purpose but in GTA V there was little point to it outside of a few missions, there were no passenger trains and no actual stations (well one if you can call it a station.)
