Psychology says people who thank drivers when crossing the street do it for more than just gratitude

Psychologists say pedestrian thank-you waves at crosswalks often signal prosocial traits, not just politeness.

The gesture is linked to empathy, agreeableness, and broader social awareness in the Big Five personality model.

Researchers suggest these small traffic exchanges can reflect how people relate to others in shared public spaces.

Such everyday courtesy may help ease tension between pedestrians and drivers.
