Fig 1 presents a picture of the AV used in this study. These vehicles are pod-like, equipped with window fronts on all sides and opposing seats, and exhibit no obvious front and rear setting them apart from both passenger cars and public transport vehicles. In this paper, we understand AVs to be shared, electrically powered, and to feature automation above SAE level 4 being able to perform at least “all driving functions under certain conditions”. The development of automated vehicles (AVs) presents a caesura in mobility revolutionising travel particularly for people in old age and with disabilities. We thus argue for broader conceptualisations of key constructs based on interdisciplinary exchange and multi-methodical study designs. Our open item for comments added valuable insights in qualitative aspects of user attitudes towards electric AVs regarding driving style, technical features, and (unsettling) audio-visual feedback. However, factor analyses did not reflect the hypothesised data structure, and validity concerns question the suitability of some constructs for attitude assessment of electric AVs.
The vehicles were accepted ( M = 1.22 SD = 0.70 range -2 to 2), trusted ( M = 3.29 SD = 0.81 range 1 to 5), and perceived as safe ( M = 3.29 SD = 1.03 range 1 to 5). 69 six of eight scales normally distributed). Tests of reliability and normality were satisfying for almost all constructs (Cronbach’s alphas ≥. As a first contribution, we bridge the gap between missing definitions of key constructs, confusion about their operationalisations, and a rigorous test of their statistical properties and data structure by examining scales on acceptance, trust, perceived safety, intention to use, and-for the first time applied to AVs-the emotions amusement, fear, surprise, and boredom. We present data from a pilot test with participants ( n = 125) after experiencing a ride in an electric AV on a large clinic area in Berlin, Germany.

After years of hypothetical surveys and simulator studies, automated vehicles (AVs) are now being tested in realistic traffic environments adding validity to knowledge about their acceptance.
