But the truth is, any bumper sticker on any car aggravates people today, from “Mary Kay Cosmetics” and “Pilates” to “We Saw The Wisconsin Dells” and “Hire A Licensed Contractor” because it personalizes the driver. And people are mad to begin with.

They think their running the world from their cells, palms and BlackBerrys but can’t even conquer rush-hour traffic. Add the quart of coffee in their system from their Starbucks addiction and no one is exactly humming, “Michael Row the Boat Ashore.”

Could your bumper sticker make you a victim of road rage?
