People may not understand how deep this goes. With municipalities eagerly allowing companies like Flock to hoover up license plates and centrally aggregate this data there is a very strong argument this is true and amounts to 4A violations when considered in total.
Add that many states have laws that are /more/ punishing if you intentionally obscure your plate than simply not having one, what other conclusion can be drawn? The state’s arguments are thin. “Oh we need it to find criminals / vehicles of interest” oh sure, so you get to suck up all our data to protect a few toll roads and track a few supposed criminals. The balance of benefit to society is dubious at best IMO.
