	Upcoming Construction The HUD displays a simplified map of the north arm of I-85 and the upcoming traffic bottlenecks and construction zones (yellow icons). Note that the electronic signage above the highway is not operational. Were it turned on this sign would display the same information as the HUD (though it would be textual rather than graphical). This is a good example of the way in which Sonopticon provides alternative channels of information rather than extra information.
	Blind Spot Check Contemplating switching lanes, the driver turns to check her blind spot. There is no vehicle present so she begins to merge left.
	Vehicle Moves into Blind Spot Just as the driver begins to move left a truck moves into the car's blind spot. The Sonopticon system senses the presence of the truck in the blind spot, displays a graphical representation of the occluded zone, and sounds an alarm that is less easy to ignore than some of the other aural cues. This decrease in ignorability corresponds to the severity of the situation.
	Visual Confirmation The driver turns to confirm that she cannot merge left. Seeing the 18-wheeler barrelling down the highway in the place that she might have been only a few seconds previously, she mutters thanks that she purchased a Sonopticon.
