Watch out for cars with bumper stickers.
That's the surprising conclusion of a recent study by Colorado State University social psychologist William Szlemko. Drivers of cars with bumper stickers, window decals, personalized license plates and other "territorial markers" not only get mad when someone cuts in their lane or is slow to respond to a changed traffic light, but they are far more likely than those who do not personalize their cars to use their vehicles to express rage -- by honking, tailgating and other aggressive behavior.

Social scientists such as Szlemko say that people carry around three kinds of territorial spaces in their heads. One is personal territory -- like a home, or a bedroom. The second kind involves space that is temporarily yours -- an office cubicle or a gym locker. The third kind is public territory: park benches, walking trails -- and roads.
