most people do it to acheive a cleaner look rather then having all this lettering crap all over the place.
im taking the lisecence plate frame back that i already took off. i took the originals off and threw them out. i go in for some warranty work and they put new ones on. so im gonna take them back and give them to them and tell them that if i ever find them on my car again that it will be the last they see of me.
^^^ cop still knew the make and model of my car when i got a parking ticket, perhaps it came up in his computer when he entered my license plate number.
