The rationale for conducting a laboratory experiment was to control for as many confounding factors as possible without exposing participants to dangers in real traffic. As such, the results are an indication of the possible effects of transition of control on situation awareness in real traffic. However, the laboratory settings were too remote from real-life situations so that nothing can be concluded about the degree of impairment of situation awareness and its duration in real traffic on the basis of the results of this study.For evidence-based measures regarding transition of control, a follow-up study is required. This follow-up study could be a simulator study in which the (simulator) vehicle drives fully automated on large road sections. In this recommended experiment, participants should wear a head-mounted eye tracker.
