Rather different views on the state of the art in truck platooning have seen some significant public activity earlier in 2019. Is it that complex to achieve real world bottom line fuel savings on public highways or public roads? What role do users – truck drivers – play when it comes to truck platooning acceptance? Acceptance issues are vital for successfully deploying truck platooning technologies. Acceptance of truck platooning may vary according to the level of automation and diverse application contexts. This paper sketches deployment paths of truck platooning and investigates truck platooning acceptance issues. Doing so, a literature review regarding truck platooning acceptance as well as empirical studies in Austria are conducted. The empirical findings confirm the trust among drivers in level 1 platoons and indicate truck drivers are rather reserved when it comes to the intention to use level 1 platooning.
