“…Highly automated vehicles, defined by SAE International as level 4 vehicles (SAE Committee, 2014), are expected to reduce driver stress and increase productivity (Litman, 2020). Challenges exist in the adoption and acceptance of higher levels of autonomy in vehicles, revolving around safety concerns with the vehicles, and can be addressed through novel interactive displays for safe transitions in automation (Jeon, 2019), such as robot agents (Lee, Ko, Sanghavi, & Jeon, 2019) or augmented reality displays (von Sawitzky, Wintersberger, Riener, & Gabbard, 2019). Furthermore, researchers have suggested the use of adaptive auditory alerts (Šabić, Henning, & MacDonald, 2019), spatial sound (Petermeijer, Bazilinskyy, Bengler, & de Winter, 2017), or other auditory displays as ways to quickly provide feedback for drivers to takeover or respond to different vehicle states.…”
