Please know that I’m asking out of sheer curiosity.The cameras are there, the screen is there and shows 3 cameras when reversing. Seems like an OTA update could make that happen if they are serious about improving the vehicles over time that way.
Turn signals already show the side repeater cameras (on the center screen). The blind spot collision detection already exists and it also can beep and bring you back in your own lane if you’re about to hit someone in your blind spot. I know for a fact that this works in all Teslas.
How would an OTA add physical lights in the side mirrors exactly?
