Automated vehicles are becoming increasingly popular. Currently, commercialized level 2 automated vehicles provide convenience by allowing drivers to perform non-driving related tasks (or secondary tasks) while reducing the burden of driving. However, these vehicles cannot fully respond to all driving situations. Thereby, during level 2 automated driving, drivers must always keep their eyes on the road and take control of the vehicle if the automated features fail to work. If the driver does not react appropriately during the takeover, it may cause traffic accidents. Thus, drivers must always maintain a high level of takeover performance during automated driving. Since visual secondary tasks (e.g., reading a book) can impair their ability to react, auditory secondary tasks (e.g., listening to audiobooks) are preferred in vehicular environments. However, according to multiple resource theory, auditory secondary tasks may also have the potential to impair takeover performance. In this study, we investigated how various visual and auditory secondary tasks impact drivers' takeover performance in level 2 automated driving environments. Our results showed that, in addition to visual secondary tasks, auditory secondary tasks can also impair the driver’s takeover performance. This suggests that, during level 2 automated driving, it may be unsafe to engage in auditory secondary tasks. Currently, commercialized level 2 automated vehicles do not monitor drivers’ auditory secondary tasks and intervene when necessary. Based on our findings, we discuss design implications for monitoring and intervening in drivers' auditory secondary tasks during autonomous driving.
