Nah, I was thinking a raw eInk panel. Not one controlled by the state. One that can flip the numbers for 2 seconds, while driving past the surveillance cameras but be back on my real license plate number immediately just in case there are any cops watching. Hell, I could even run recognition against the rear dash cam, so that it overrides a flip if there are recognizable cop cars within view. Could be fun.
I equate these license plates with terrible money management skills. $900 for a license plate: "a fool and his money are soon parted" regardless of what income bracket they're in
I observed very similar behavior a few years back when transferring files between two servers under my control on different parts of a large university network.
We also initially thought we were the subject of a breach, but after the investigation we determined that the network's IDS was monitoring all traffic, and upon certain triggers, would make identical requests from external networks.
We found a way to identify all other similar IDSs across the internet and even "weaponize" this behavior. We ended up writing a paper on it: https://ian.ucsd.edu/papers/cset2023_fireye.pdf
