I heard on the news today that putting offensive bumper stickers on your vehicle makes it 20% more likely (I don't remember exactly how much, but it was around 20) to get into road rage. Some examples are: My kid just beat the crap out of your honor-roll kid; Keep tailgating! Your right in range; and Keep Honking! I'm Reloading.

Since I'm new to the roads, I was wondering if you guys have found any icrease in the incidents with bumper stickers.
