    Head-up displays (HUDs) present opportunities and challenges for mitigating driver distraction. HUDs may improve safety by reducing the time required to view driving-related information relative to a traditional head-down display (HDD). However, because the HUD is in the driver’s field of view, drivers may fixate on it and fail to perceive events i ...
