At the end of the day, it takes 24hrs to order new plates. There are enough places where you can order plates that aren't legal, i.e. wrong font or whatnot - won't even have to show any documents. So not sure those bolts serve a decent purpose. Same as blacking out number plates on photos. At the end of the day, all it takes is opening your eyes on the street to 'get' a new plate that matches your car. So don't see the point. Or am I too naive there.
