That's odd since Tesla seems proud of their AI expertise. Isn't something like "image is blurred" a fairly pedestrian (heh) exercise? Especially given that you would have related data, like what speed the car is going, if you're parked, etc.
They do report if the camera can't get a good image. Glare from the sun is the most common reason. It is certainly possible that there is a window between when vision is degraded enough to be dangerous and when it alerts the driver, but a single occurrence isn't proof of a widescale problem. That is the type of thing that should be investigated in more depth, but it is hard to get anyone to care when it is only a theory that isn't even yet connected to a single accident.
