This cover sounds like something that could easily be illegal depending on the location.

Quick research says that license plate covers are "Allowed" in just 16/50 states, though I have no idea how accurate the source is and it also says that the "Allowed" designation "only" means that that that state requires license plates to be easily readable. (One of the table rows is "Arizona: Arizona | Arizona", so perhaps it's not very accurate.)

Still, regardless of how reliable the sources I found are, I'd be shocked to find many states that don't have prohibitions on making it difficult for red-light/speed/ALPR cameras to read plates.

Luckily most states have provisions that don't allow red-light / speed cameras in general. And we should keep it that way.

It is insane that I can get accused of an infringement by a piece of software. I have the right to face my accuser in court. Who are you going to put on the stand? The camera? The CEO of Gatso?

ALPR is done for turnpikes & some HOAs are deploying them to track who comes in and goes out.

While I don't condone getting a cover for the purpose of avoiding taxes on turnpikes, I do condone them for avoiding ALPRs to avoid private companies from tracking me.
