Answer: The driver saw the boy because it was during the daylight hours.
All the electricity was out in town and none of the street lights or traffic signals had power. A dark limousine was cruising down the newly paved blacktop, with its headlights off. A young boy dressed totally in black (with no reflectors) stepped out to cross the street. The moon wasn't out and the boy had no flashlight, yet the driver stopped to let the boy cross the street. How did the driver see the boy?
