I think its funny you think youve come up with some unscannable license plate.

My state does not allow certain confusing characters, but I'm part of an organization which issues plates in specific violation of aforementioned character restrictions (as an added bonus the plate/organization is emblazzened with `EMERGENCY` across the bottom). ALPR camerae mis-read the plate, having applied state interpretation rules — no human outside my organization has ever read it correctly, either [0].

But of course since you cannot even see it anymore it is definitely unscannable. I can drive by speed camera without issue (i.e. no citations received; not that I regularly do, but have tested).

[0] Only once have I been pulled over, in the past decade (back when plate displayed normally), after traveling behind a cop for miles going 100mph+ through Dade County mountains. Cop: "I have no clue what agency you're with — you're plate didn't scan — but you need to slow the fuck down. You're lucky I have somewhere else to be!"
