Doesnt prevent taking two or more plates, splitting them vertically and re-combining them.
You can't defend against everything, but any criminal who defeats the current license plates wouldn't have been caught based on his license plate anyway.
The font is enough to make plate manipulation not worth the effort for average criminals and for people trying to defeat speed cameras. Going any further than that isn't worth the effort.
Isn't that basically any decent sized metal press?
If it only has to look the part, 3D printing plus paint will likely do it without the outlay.
This is not a sophisticated anti-forgery scheme, it's a no-cost layer of tamper resistance.
If you can find retroreflective foil that looks close enough, a cheapish 3d printer and a good paint job might indeed work great as well.
