So you can buy an online version for $12.99 here. It does have interesting information for design geeks as well as others. I've excerpted as much as I think I can get away with below.
Other tidbits: Rivian isn't kidding when they said they have very tough durable interior materials. Their storage tunnel and seat backs are made with SuperFabric, which is used in motorcycle jackets to withstand abrasion from road surfaces at 60 miles an hour. Floor mats look like carpet, yet can be hosed clean. Cool - the seats have a storage compartment under them. It all sounds top notch and I CAN'T WAIT!
