Went to inspect my 2018 model S (should have been vehicle hand over, but didn't happen!)
Both B pillar cameras full of condensation. I was told same thing: will clear when you run the a/c. Of course dehumidifying the air inside will eventually help, but the issue is that when humid air is trapped inside (like every time the floor mats get wet, rain soaked jackets come into the car, your wet dog gets in the car, or even whenever general humidity levels are high) and the outside temperature drops, you will get condensation in those camera windows.
This strikes me as a potential safety issue, especially as FSD eventually finds its way on to more cars. Changes in inside and outside temperature happen all the time - sometimes suddenly and extremely. This will be a nightmare for image processing to deal with as it must surely increase the chance of mis-processing of unpredictable images (eg: impression of fog only on one side of car, sudden loss of image due to Sun glare on condensation).
Just like automatic cabin temperature adjustment (to deal with using consumer grade electronics in a harsh vehicle environment), do we now need to see automatic humidity control to deal with poor sensor design? And should range figures take into account having to run a/c all the time, just in case? Does the car have a recirculation mode for a/c - because in other cars I have found that this can lead to rapid changes in cabin humidity levels under certain circumstances.
This might not effect cars in Southern California, but there are different climates that cars can be driven in!
I would really like to hear experience of owners in other colder climates - Norway / Sweden.
