Is there something missing or is it Just a Design Flaw ?? No matter the Weather and Road Spray my Right Side Camera under the Mirror is always Clean & Clearly Focused.. But the Camera Rear Facing No matter the weather & road spray , complete different story .. Doesn't take much and what you see is a completely distorted picture thanks solely to the Elements .. Question, is there something missing such as a Deflector over the Camera Lenses or it simply a Design Flaw ??
