Misleading Rivian Route Planning Bias?

The Out of Spec team has been running an R1S DM Max press car in their recent Ft. Collins CO to Las Vegas road trip 'races', and experienced some strange route planning behavior along the way. We've never seen this before in our R1T DM Max, on our recent 4,500 mile road trip to Texas and back and along many of the same driving segments they had issues, or right now just plotting a trip to Ft. Collins...so what is going on here?

Agreement with your video. Kyle @ OutofSpec's reviews can be a little sketchy with some of his statements made in some of OutofSpec's content.

As soon as I saw the video I checked and I didn't see preference for RAN. But I think I did in the past. I think they may have tweaked the software. I have seen bad route planning. But they are getting better with time.

I wonder if the Out of Spec team unknowingly had the charger ratings limiting charger locations in the Rivian nav. If the EA station they wanted the Rivian to route to had a 'C' or lower rating and the nav was limited to selecting 'B' or better rated chargers, it would explain the preference for the Rivian waypoint charger.

Yes but, to be clear there are no 'charger ratings' in the onboard route planner, as shown in this video. There is for the Nav map charger display filter, and while that _could_ trickle down to the route navigation settings, nothing else does so not much reason to imagine ratings against all odds, do.

Another theory I have is the minimum arrival on intermediate stops forced them to that waypoints charger rather than arriving with a very low SOC at the EA charger.

[@MotorsportUnplugged]

Agree that's a possibility, Rivian doesn't currently allow a way to set the minimum SOC at those mid-waypoints. ABRP sure can, so hopefully that trickles down before long.
