I'm seeing more and more 'greyed out' number plates (front and rear). The plate is barely legible but seems designed to (a) show off and (b) blend in with black or grey cars paintwork. I see them on large SUVs, many with tinted windows etc. I fully accept that I particularly notice them because I really don't like these ostentatious behemoths cruising around suburbia. The fact that nearly all the plates I've seen are personalised merely reinforces my prejudice. What is the reason for them? Are they legal? If not, how can a manufacturer be allowed to produce them, bearing in mind the number of regulations which apply to number plate manufacture and supply? Best wishes.
