I'm surprised there's so much effort to make faking plates by using black tape harder. Let's assume somebody successfully does that. After the accident or whatever, they check the plate and it belongs to different kind of car. I would imagine there would be no more than 10 options of plates which could result in this one + black tape. And you find confirmation by checking if the car color and brand matches. It could actually be automated and should be easy even if there would be hundreds of possibilities.
