> Rivian's OBD-II port actually hides an Ethernet signal inside of it - so the interface is certainly there.

Nice. This is really normal now, for what it's worth - all of the European makes have moved this direction as well (DoIP over ENET). There's shockingly little documentation about Rivian online, though, probably because emissions regulation doesn't mandate it.

For those unfamiliar with DoIP:

    The first link leads malicious ads/malware. On iphone says viruses detected pretending to be apple/google

      I don't see anything suspicious, but I browse with scripts and ads blocked, so it's possible that you encountered something that never reached me. Thanks for the warning. Unfortunately, it's too late to edit my comment.

Yeah, I got a cable to update my 2017 BMW's infotainment system, and it's OBD-II to RJ45. Doesn't seem to be too new of a thing.

    Yep! Depending on the vintage, BMWs have "real" DoIP or a BMW-ized version (sort of like how KWP2000 was the predecessor to UDS). For emissions modules, they still also have to support updates over UDS as well as ENET, though, for the above mentioned J2534 reasons (Ethernet wasn't added to J2534 until 2022).
