That's good to know. I showed this feature to my wife on the evening that we got the car and while it was still grubby from being on the hauler and was still raining. I flipped it over to the camera view and since the lens must have been wet and dirty the view was murky and lighting from cars behind us looked strange, kinda like the graveyard scene in Disney's Haunted Mansion. So we quickly switched it back to what we were used to seeing as that is just fine as long as there are not tall people or rear luggage blocking the rear view, and decided to give it a try another time.And, the washer cleans both rear cameras well from any dust or dirt on the lenses. Not sure about freezing weather though.
