Well, the still are required by Federal law to report their data to the NMVTIS, on a regular basis, which means, if someone pulls some kind of stunt using a number that is active in another state, it won't matter that Iowa is not the one keeping the records. For perspective, there are fewer people in Iowa than there are in the City of Los Angeles. Not the LA Basin. Not the LA metro area, just the namesake city in the center of all of that. The LA metro area alone, has 4x the population of Iowa, and it is not the only large metro area in California. It already happened here, and in-time, it will happen to every other state. The computer systems used will break down, and be no longer serviceable. When that happens even the most bare-bones, entry-level systems sold to the smallest states, will have the capacity to store every present, and potential document. It is not speculation, it is Entropy, and the Second Law of Thermodynamics. Neither cares what your opinion of either is.
