Now when we've got updated rain "fysics" comming. That gave me a thought. And that thought was to ad (if posible) random swarms of bugs or insects to the game. As of now you are basically driving in a sterile enviroment. You don't need to use the wipers unless it rains. If you could drive along and hit a random bug swarm that clutter up the windscreen. So you have to use the wipers clear up the "bugy mess" so you can see out clearly again. We already have water effects why not a "bugy" effect. Anyway I thought that could be a interesting feature to ad.
Seems like a cool idea to be honest. If this feature wouldn't cause any issues or bugs (no pun intended ) then I don't see why not.
It could be something similar to dynamic weather which is also dynamic at runtime and not predictable.
