Regular number plates are always safer. Except for those thousand people who were issued plates after KKJ-999.
Too bad there are more than a thousand people who would want that one...
I have always let the state pick my plate for me instead of paying even more taxes. Some people think that plates are something you go out and buy because it's something they desire.
I remember a Texas plate HMFIC2. Most Army veterans will quickly translate this (could have a racial slant) but why Number 2?
