We will also add an explicit paragraph acknowledging that the survey is necessarily limited to publicly available sources and cannot claim exhaustive coverage of closed OEM/Tier-1 implementations.

The SDIoV section ties SDN ideas to vehicular edge computing in a straightforward way.\n\nThe limitation is the usual one for surveys: coverage depends on what has been published openly. A lot of SDV work sits inside OEMs and Tier-1 suppliers, so the review may miss recent or proprietary details that matter for real systems. No new mechanisms, data, or derivations appear; it synthesizes what is already out there.\n\nA reader who wants a structured starting point on automotive software platforms would get some use from it.
