Change the law surrounding the display of private number plates on vehicles

Plates are a way of identifying a vehicle, as long as this can happen without obstruction, I see no reason why the DVLA or law should restrict something within reason to be modified to suit the buyer as long as the font remains consistent and not modified in any way, no adding of screw caps or tape to change a fonts appearance should be allowed, purely the spacing of the letters from the next should be acceptable and allowed as long as the plate can be clearly read and understood.
