Honor students, America, political figures, and the environment are all subjects that are routinely displayed on a bumper sticker. I’ve never been one to display my political or social beliefs on a sticker on the back of my car, but it seems that many people enjoy displaying things on the bumper of their car. To each their own, but some drivers feel that they must wallpaper the back of their car with just about every conceivable sticker they can find. It turns out, that the over use of bumper stickers may have a correlation with incidents of “road rage.”
Dale Jewett, citing a Nature article in AutoWeek, writes about the possible correlation between bumper stickers and aggressive driving:
“The number of territory markers predicted road rage better than vehicle value, condition or any of the things that we normally associate with aggressive driving,” psychologist William Szlemko said. “What’s more, only the number of bumper stickers, and not their content, predicted road rage.”
I’m not sure of the merits of this study, but it sounds legitimate enough to me to keep bumper stickers in high numbers off the back of my car.
