From across the intersection, I watched as a car hesitated when the traffic light turned green. Then, out of nowhere, a voice began screaming, “Go! Go! Come on, go!” The driver appeared frightened by the angry cries, and he was a bit confused as to where the voice was coming from. Then I saw it—the car behind him was equipped with a loudspeaker that enabled him to yell at other drivers! Eventually, the hesitant driver collected himself and moved along. I was struck by the rudeness and impatience of the angry driver.
