It was one a.m. and Guy Halverson sat in his dark living room. He hadn’t moved for over an hour. The accident earlier that evening kept playing over and over in his mind. The light turned red, but he was in a hurry and accelerated. An orange blur came from his right, and in a split second there was a violent jolt, then the bicyclist rolled across his hood and fell out of sight on the pavement. Horns blared angrily and he panicked, stepping on the gas and screeching away from the chaos into the darkness, shaken and keeping an eye on his rearview mirror until he got home.
