Drivers with attitudes
Beware of vehicles that sport bumper stickers, warns a social psychologist at Colorado State University: They signal that the drivers have an attitude. It's not only bumper stickers that tell on a driver, but also window decals, personalized license plates and other "territorial markers," says researcher William Szlemko in the Washington Post. Apparently, it doesn't matter whether the messages urge support for "whirled peas" or warn other drivers to back off because "the voices said to stay home and clean the guns." Any message on a vehicle conveys territoriality, and that's the link to road rage: Easily angered drivers "tend to think of public streets as 'my street' and 'my lane' -- in other words, they think they own the road."
