Red Light Distraction

As I was pulling up to a red light, the main chorus of Katy Perry "Roar" kicks in on the radio so I figure I'm okay to rock out for a second in safety and seclusion. I made the mistake of looking to my right and there's some dude in a truck wearing shades with a beard down to his gas pedal, he looks at me, shakes his head and then faces forward to never make eye contact again.
