Nobody is saying its impossible, its quite possible. Just trying to figure out the logistics of it. Maybe a SC visit where they install a hard drive somewhere would be my guess. I was thinking usb sticks for video storage, but that seems so unreliable considering the relatively slow data rates of USB.
or maybe all teslas have a secret 1TB hard drive installed somewhere we don't know about
