Collision repairability seems to have not been a factor in the Rivian design.

Ouch. That seems to be a common story with EVs. They have all kinds of sensors and cameras and wires. It’s not like A regular car where you just put a new bumper on. Some of these new ones have unibody designs, so you can’t even replace a quarter panel and with all the sensors and wires you can’t just bang dents out either. I don’t know the specifics on that car or that accident but I have heard stories of Teslas just getting totaled by the insurance company. Cheaper to replace than repair.
Another function of the cost may also be lack of parts. Tesla parts are all Tesla parts. Maybe true of Rivian. They don’t have aftermarket supplies or parts made by 3rd party vendors so you gotta buy them directly. And, as the story said, only 3 certified techs who, while certified, may not actually have a lot of real world experience. It’s a new car company with not a lot of cars on the road so even if certified they maybe never did the job before. So there is no competitive pricing and the work may take longer.
