What driving style makes pedestrians think a passing vehicle is driving automatically?

An important question in the development of automated vehicles (AVs) is which driving style AVs should adopt and how other road users perceive them. The current study aimed to determine AV behaviours contribute pedestrians' judgements as whether vehicle manually or automatically well likeability. We tested five target trajectories an curves: playback manual driving, two stereotypical conditions (road centre tendency, lane tendency), conditions, slowed down for curves cut curves. In addition, four braking patterns approaching a zebra crossing were tested: braking, (fixed deceleration), variations (sudden stop, crawling forward). was observed by 24 participants standing on curb groups. After each passing AV, rated car driven automatically, degree they liked AV's behaviour. Results showed that trajectory considered more than conditions. stereotype ‘road tendency’ ‘lane received similar likeability ratings driving. analysis written comments curve cutting reason believe manually, whereas at constant speed associated with sudden stop least likeable way decelerate, but there no consensus this behaviour automated.
