If 4 cameras are for parking like mobileye's implementation then that means 13 - 4 = 9 cameras or one additional camera for driving? Or is the indoor cabin camera counted in the 13 count? Then no additional FSD cameras for HW4, just 4 additional parking cameras.
I'll start a new rumor: 2023 vehicles will come with parking cameras or 360 park view.
