If they're all together like his are then I don't think much can be said about them, there isn't enough room too have the plate both spaced correctly and the proper font size, so he'd have to sacrifice one or the other, I think it's when the plate is mis spaced, ie if the numbers were split instead of together like **5 4*** instead of **54 *** but that's just what I think.
Also the german plate should be fine, because you're plate doesn't have a 0 then it looks like any other plate, I got given stick by the cops with my plate because there's a 0 and the german 0 doesn't close off. Otherwise it's just the D.
