Won’t snow/dirt accumulate on any surface? It would be an issue in any situation from what I can tell, unless you have a way of remotely cleaning the surface in question.The rear view camera migt be mounted in front of the bed closure unter the glass roof. than there is no issue with snow and dirt.
My Range Rover has a nozzle that washes the rear camera - works pretty decent. If all the CT
cameras have accompanying washers or some other way to self clean, shouldn’t be a problem. But it will be challenging to have that feature yet keep everything streamlined. Good thing Tesla likes challenges...and are pretty good at finding solutions.
