Sitting from my armchair here is sunny Perth, Australia, I sometimes do wonder why the UK cannot just move into the 21st century and relax the number plate 'rules'! Gone are the days of bank robbers escaping in the black V8 Rover, with a member of the public proudly telling plod they could clearly read the licence plate! It's a lot easier to remember 'FAST PLUS 6' than BH19 FDK
ANPR systems are so robust, virtually any font/spacing/colours can be read... as is the case here in OZ where you can have virtually any shape/size/colour/font/spelling etc of number plate, supplied by the various motor registration departments!It's a great money spinner for them and people get the numberplate they want.
As for insurance being 'null and void' because of an 'illegal number-plate', that seems just totally illogical and utterly ridiculous! What relevance has an 'illegal font' number plate has on whether you crash you car... NONE!
