I've got a Rivian and have only used their chargers on a road trip to Whistler from the Bay Area. One was in Shasta behind a little hotel—you'd not see it if you weren't looking for it. The other was at a Homewood Suites lot somewhere in Southern Oregon. Unsurprisingly, these were back-to-back stops. So, I think they were specifically put there to help bridge a gap between Northern CA and Southern OR.
