Weiner, you're thread brought to mind these games.
European Truck Simulator 1 and 2. American Truck Simulator.
My wife laughs when I play these. She says it's funny because I'm always hitting keys or moving the mouse around a lot when I play, but on these, it's so quiet and I just move the mouse slightly to the left, or slightly to the right while hitting keys every now and then.
These things are addictive though. Something about them.
