I also own a Tesla, and there is no indication shown to the user that FSD's vision is degraded. They need to add this in.

For example, numerous times I have been driving my Tesla with FSD activated with ostensibly a clean and clear windshield when suddenly the car will do the "clean the windshield in front of the camera routine" without any indication that the car's camera is degraded. If people haven't seen this "clean the windshield routine", the wiper fluid is dispensed and the wiper will vigorously wipe in front of the camera only -- the rest of the windshield only gets a cursory wipe.

This indicates to me that the camera has poor visibility and I am not informed or aware of this as a driver, which is concerning. I am often curious if there is a thin occluding film on the windshield in the camera box in front of the camera, or something that has degraded FSD's vision, but they do not give you the ability to view the camera feed, nor do they notify you that the vision is degraded. I think a "thin occluding film" may be in the camera box because my normal windshield outside of the camera box started to show a thin chemical film after a couple of months, which apparently (according to a Google search) happens when a new car off-gasses, adding a thin film of chemical byproduct to the windshield. This is my first new car so I've no idea if this is normal or not.
