Well I don't find anything wrong in it because Number plate is something public, displayed at front & back for everyone to see... It is never meant to be confidential...
I am also surprised at PW Ad posters who edit number plates in the pictures (Although I also followed this trend religiously ),,,, I mean do you think some thief is writing down numbers from PW to make fake number plates???????????? Are there not enough number plates on the road to copy the digits???????????????????
