I'm not sure. But I'm going to start carrying donuts in my car. There was an officer behind me on the way to work TOO! I slowed down and moved over in front of a Lexus. The Lexus got annoyed and pulled into the left lane and started to accelerate. Thought for sure that the cop would go after it. Nope! The Lexus figured things out in a hurry and pulled back into the middle lane!
