Bah!
The UK plate system is idiotic and outdated anyway. The British idea of a "personalised plate" is laughable as a result.
The DMV should have realised the market for properly personalised plates years ago and begun a project to make it happen so it could be monetised.
And before anyone feels the need to explain, I understand how the UK plates "work", and the difference in the way they are allocated to that of the USA. I owned cars in the UK for over a decade and once could read a car's birth certificate (so to speak). I lost the skill when literally everything else became important.
There is no reason that plates couldn't be designed to convey the *important* registration info while at the same time allowing the freedom that US drivers have, should they wish to do so, to parade around with a personal message on their bourgemobile.
Personal fave: "DETHTUNG" on a Corvette back in the 90s.
