> 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.

Older cars have no concept of such updates.

Happy with my 70s and 80s and early 90s cars.
