Rivian semi-bricked all their cars with a busted OTA update

Rivian, that US electric car company that makes massive and expensive SUVs and utes that are kinda nice if you're into that sort of thing, pushed out an update to their fleet of vehicles that bricked the entire infotainment setup. While the vehicles can still be driven, the screens, including the instrument cluster, are blank. Rivian said on Reddit (of all places?) that the cause is a "a fat finger where the wrong build with the wrong security certificates was sent out" and the only way to fix it might be "physical repair" - i.e, taking it back to Rivian. OTA updates are great when they have new features but really suck when mistakes like that happen that probably shouldn't in a more robust production environment.
