I won't be changing my plate and I'm happy to pay the fines.
None of the copper have ever said to me that they will issue me with a strike, send me to a MOT station or anything else. Just a simple "get it changed".
I actually like plates that say your name or initials. What I do hate is ones that read obscure words like B005TED or B16 W1LY or PU55 KAT
