I think that it would be a great idea to have functional windshield wipers that can be turned on and off and when done the windshield wiper switch would flip or turn in the interior of the car. Something else that would be cool is if the radio in the car would say what song your listening to if you are listening to a song. Lets say you have Spotify open in another window and your listening to Blue by Eifle64 on the radio screen in the car your in it would say (Blue-Eifle64).
Harder then you think it is to do. There is a mod for moving windshield wipers, just saying. I think it is called the more features mod.
yeah i know about the more features mod but these are just suggestions and of course it wouldn't be easy
