I have a garmin watch which is great for overland hiking, multiple day expeditions etc
I download the maps and the watch has GPS to plot where I am on that map. My watch doesn’t have an eSIM at all.
Rivian is an adventure brand so if they wanted to design a maps system like that, where I am not continually downloading tiles from open maps or google and sending my location to them and others, they probably could
I just don’t think they have space for those types of features most people don’t care about while they are trying to compete in a rough industry and deliver new vehicles
The experience was even comparable to today's experience - I've been auto-routed around a road closure, like, twice in 5 years? And it _failed_ to route me around a road closure probably twice as well?
Also, there are now several countries that sent positioning constellations (obviously to not have to rely on the US for positioning), and most receivers support several: GPS (US), Galileo (Europe), Glonass (Russia), Beidu (China).
