Wrapping the car might be problematic because the law regulates where the number plates are located on the car, what they look like, their size and colors. In some places it’s criminal to display illegal number plates, this would most likely qualify as such.
I think you could successfully argue that any human could clearly tell the difference between paint with numbers on it and real license plates.
A human indeed.
I could see the police saying you did it intentionally to thwart them, but again, it’s not illegal to wear body armor in case the police shoot you. Suspicious, sure. But not illegal. This is exactly the same thing, except from AI, instead of bullets. Suspicious, yes, but not illegal.
