License Plate Sabotage
…for a number of years I have toyed with the idea of getting a personalized plate with II11I11I or 0OO0OO00 or some such, on the theory that there is no possible drawback to having the least legible plate number permitted by law. (If you are reading this post in a font that renders 0 and O the same, take my word for it that 0OO0OO00 contains four letters and four digits.)
