I have seen this kind of behavior at other lights at Trail crossings. I tend to get mad. But not for too long. I try to get a good look at the type of vehicle, the driver, and the license plate number. I then visit the Fairfax County Police Aggressive Driver Report Form where I describe what happened. I've been told that a letter is sent to the vehicle registrant about their bad behavior.
In this case, I hope the motorist was decurled.
