Taking a nap during an automated ride - sounds like a future dream and promises drivers relief from feeling sleepy. However, benefits of sleeping may be opposed by sleep inertia - the post-sleep grogginess. Beneficial and detrimental effects of sleeping behind the steering wheel may depend on several factors. As part of the project #RUMBA, which is funded by the German Federal Ministry for Economic Affairs and Climate Action, WIVW investigated the role of the time of day and individual predispositions like the chronotype on driving under sleep inertia.

The study is now published in Transportation Research Part F: Traffic Psychology and Behavior and is freely available for 50 days at Sciencedirect: https://authors.elsevier.com/a/1ibK%7E_V9P1IseO
