It would be excellent to see heat haze effects added in into the game on hot weather conditions. To be able seeing heat haze rising from road surfaces, building roofs, dusty plains and in dried out grass fields or beaches.

Similar to what Mad Max game has in hot hours of the day.

Also see mirage effects on road surfaces in the distance on long roads would make it more immersive and appealing than looking at a road that seems to be quite flat and repeating with not much variance in textures and looks up to the horizon of the road.
