I suspect what we might be running into is similar to the California laws related to bringing a vehicle in. A California resident must possess a valid temporary California registration for a car in his/her name within 15 days of the vehicle arriving in-state (at least I recall it being 15 days).
Technically, in some states it may be illegal to operate a vehicle with a California temp tag for more than a short period of time, because the laws may state that residents of the state must have a local registration within <x> days.
I was lucky in that Tesla delivered my car with an IL temp tag, so I didn't have to deal with it. For those who had issues with the California temp tag, I've heard several times that it would have been far more beneficial for Tesla to provide the MSO/MCO and let the owner go to the DMV.
