I don't think there's any up to date wipers mod. BeamNG doesn't have rain either so I doubt it'd be useful for anything anyway
there was a really old windshield wipers mod from 2017. It actually broke so someone fixed it in 2020. I am not sure if the fix still works nowadays though. The fix only worked with the sunburst anyway.
In this post, nadeox1 said that wipers haven't been implemented for now. that post was in 2015. Could it be in the works? Who knows? (and in the same thread, another staff member said there's something hidden in the jbeams. anyone knows what they were referring to?) They said it's something that maybe would be implemented in the future. Vanilla working wipers?
Wipers means weather Weather means ground effects Ground effects mean deformable terrain Deformable terrain means good, probably
The thing hidden in Jbeams is wiper stalks being able to move like the indicator stalks, but you can't control them. Not sure if that is still a thing or if it got removed at some point.
