Would really like to see a weather system and changes to the way that dark looks in this game. Hail, rain, snow, thunder, lightning. All of these would of course affect your driving. Dust storms too would be nice. Ice in roads, hydroplanning, etc. Also, darkness in this game is terrible. Headlights don't do any justice when its dark, they light up like 7 inches in front of you. Its terrible driving at night because you can't see anything.
There is a change to night mode, if you go to Environment and press play the time will go up and down.
Yeah when I have all my lights on in utah map the game is basically unplayable but maybe it's because of my potato's settings. Either make brighter car lights or improve dark environments for potato boys
