Why Don’t More Games Tackle Transportation’s Environmental Effects?

It’s interesting how many simulation and strategy games focus on building efficient transport networks, but few seem to dive into the environmental consequences. Trains, roads, and airports all have real-world impacts like emissions or contributing to urban sprawl why isn’t that explored more? I’ve seen a handful of games touch on it, but it feels like a missed opportunity for deeper gameplay. Maybe it’s seen as too “niche” or complex? Or do you think players just prefer to avoid those trade-offs? Would love to hear if anyone’s come across games that handle this well or why others might shy away from it.
