Oh, definitely. However, usually that's the way I identify the correct driver. For instance Priuses are the more common car and sometimes it's easier to memorize the first 4 or so digits on a plate than the make/model/color that my driver is driving. But on the other hand, it's still a small issue at least because in some rare circumstance somebody could use it maliciously.
