Does prior experience influence trust in novel automation systems? A study on two mobility platforms

Rapid advances in shared mobility and vehicle automation have led to a monumental shift of interest toward developing automated systems. However, automation development has wider implications for how end users would trust these novel automation systems. This research explored how the experience with prior automation systems and exposure to vehicles of similar form factors may influence trust when they would encounter novel mobility with a similar type of automation and form factor. A simulator study was designed with 48 participants when they interacted with AV cars and AV sidewalk mobility. Participants engaged in a simulator study consisting of two interactions separated by a few hours. Findings from the self-reported surveys suggest that prior experience with ADAS features and the preferred driving style of participants influenced dimensions of trust.
