alt Hacker News> I wonder what happens if you disable the e-SIM (in the US) and then a safety recall appears via software update - do dealers have any way to update control modules besides OTA?
I would assume so. Even on older cars, service techs can typically manually push firmware updates over the OBD-II / J2534 port. Rivian's OBD-II port actually hides an Ethernet signal inside of it - so the interface is certainly there.
Fun fact: You can buy an Ethernet adapter directly from Rivian here to connect to the car's internal network: https://rivianservicetools.com/Catalog/Product/TSN00535-300-...

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.
