Trusting autonomous vehicles is seen as crucial for their dissemination. However,
research on autonomous driving so far is restricted by using closed training courses or
simulators and by comparing behaviour and evaluation while driving oneself (a manual
car) with being driven (by an autonomous car). In the current study, we investigated
passengers’ eye movements, categorized as safety-relevant or not safety-relevant, and
trust ratings while being driven, once manually and once by an autonomous car, in real
traffic as well as in a simulator. As some of the effects observed in the field experiment
might have been caused by driving style, driving style was additionally varied in the
simulator. Fixations in safety-relevant regions (e.g., on the road and steering wheel)
were observed more frequently during safety critical driving situations than during
regular driving. More safety-relevant fixations for the autonomous compared to the
manual driving mode were observed particularly in the field. Trust ratings were affected
by driving mode mainly in the simulator: Here, being driven autonomously led to a
lower reported trust than believing to be driven by a human driver. Driving style
showed to affect trust ratings, but not gaze behaviour in the simulator experiment.
Correlations between gazing into safety relevant regions and trust ratings were of
smaller descriptive size than in recent investigations on drivers, suggesting that gazing
into safety-relevant regions as objective alternative to trust ratings may not be as
exhaustive for passengers as for drivers.
