I thought you weren't supposed to smile for driver's license photos, something about it being more difficult for face recognition software.
Only in Arkansas, Indiana, Nevada, New Jersey, and Virginia. Although Arkansas, Indiana, and Nevada apparently allow very slight closed-mouth grins (no pearly whites) which make you look like every mugshot of a sex offender you've ever seen on TV, so there's that.
31 other states also do computerized ID matching, but apparently they invested in better facial recognition software that can't be foiled by the high-tech Q-Branch countermeasure of smiling.
One can only imagine the kind of deviant psychopath practiced in the dark art of human emotional mimicry that it would take to be able to summon a smile after standing in line at the human slaughterhouse that is the DMV for three hours. That these sick criminal masterminds walk among us at this very moment, waiting to strike, because of substandard facial recognition software gives me chills.
