Gonna go off on a tangent here about how people almost certainly shouldn’t focus much on camera calibration.
FSD is everything to Tesla now, the key to Tesla reaching many many trillions of dollars in valuation will not hinge upon needing to hit an extra button in some menu. If camera calibration was ever that important or necessary, Tesla would build the system such that it either calibrates with every new update or better yet goes through a self-calibration every time you start the system. If and when robotaxis ever arrive, I imagine that is exactly what will happen and there will need to be processes built in that ensure the cameras are always properly calibrated like pilots going through all the pre-flight checks before moving down the runway — except without needing a human to do it, because autonomous robotaxis.
Right now if camera calibration was necessary to ensure good experiences for users and therefore subscription revenue, it would not be an extra step.
