Idea translated: nº 7148 of ideator Hugo_10vkHaven't you ever been driving on a super rainy day, so that when you want to change lanes, you realize that, because of the raindrops on the window (through which you would need to see the rear-view mirror) you can't see the distance between your car and the car driving coming from behind? What I suggest is a small wiper with an absorbent cloth that cleans the window from the outside of the door, letting us see the rear-view mirror clearly. To improve on safety, you know.
