Alex from E for Electric is a youtube influencer, not a journalist, and as such usually has a lot hearsay and conjecture. In this case, it's not his fault as Rivian has virtually provided no information about their subscription model. RJ has mentioned a subscription model over a year ago in August during a Bloomberg interview. We basically know no more now than when he mentioned it last year.

"Would you consider signing up for a Rivian subscription instead of buying a R1T or R1S? "
Since I tend to keep my vehicles until they almost die, I would probably not use the subscription model as most are usually beneficial for those who change vehicles more frequently. On the other hand, I would consider it depending on how they structure the subscription model(s), e.g. what would be the minimum term, cancellation fees, change/upgrade vehicle fees, etc. The reason I might consider this plan is because these are introductory EVs that could be problematic. And even if they're not, I'm sure upgrades will come along that can't be done OTA but instead only available with a new model. So making an assumption I'll really like my Rivian EV, perhaps I'll only keep it a few years (ala subscription model) and replace it down the road with a newer/better Rivian model that I'll keep (buy?) for the long term. Again, it all depends on how they structure the subscription models.
