Yes, that is def one answer. The other answer could be related to proprietary tech with (what looks like) a seemingly traditional 5 bolt pattern, that isn't actually compatible with anything. Do we have specs on bolt sizes, thicknesses, lengths, heads, materials, anything? What about the actual wheel design potential modifications made there? The only reason I bring that up is because we just don't know yet if this is really the same old traditional 5-bolt pattern, or if it is something entirely new. If I were Rivian, I would want to launch with something new that wasn't easily replicable for 3rd parties (at least for the initial outset) at a minimum to make my trucks look distinct and to let them be individually recognizable. If someone could easily replace my wheels to change the appearance of the vehicle to make it look like something else (that Rivian could not control), would I want that as Rivian? Probably not. Maybe I am way too pessimistic, but could Rivian benefit by establishing something proprietary and making it necessary for us to purchase a second set of wheels directly through Rivian (at least to start)? I don't know the answer. All I know is that industries set and change standards all the time to manufacturer's benefits, and to get us to buy more (and potentially better) stuff. Sometimes to the point where consumers are pissed off, like when apple makes intentionally obselete charging cords or peripherals that wont work when you buy a new iPhone, but you need the new iPhone, so you buy the new crap to go with it.
