Very nice, but quite frankly "personalised" number plates are amongst the most naff additions to vehicles imaginable. This is particularly so for those like the one mentioned in the question. It MAY mean something to the owner, who knows? But for the rst of us it is a nonsense.
All vehicles need to have number plates and thee should be of the type approved with the correct font and spacing, no spurious "bolts" to alter letters and nothing to make them easily readable. Penalties for transgressions perpetrated by vain individuals should attract hefty fines and a minimum of six penalty points.
