Well that's what happened to people in Texas recently, when malfunctioning streetlights started flipping people the bird.
Sets of lights in the City of Amarillo suffered a fault whereby not all of the lights, which make up the hand on the stop light, were illuminated.
This gave the effect that the normal red palm had become the hand gesture of sticking up one finger at pedestrians.
City officials say they've already had to replace at least six of the offensive cross walk signs… only drivers are allowed to be that abusive to walkers.
