This article responds to the uncritical use of chronological time and the strict division between past, present, and future when thinking about mobility behavior or mobility decisions. On the basis of this critique, it introduces the concept of intentional automobility, which relies on the Bergsonian–Deleuzian conception of time—duration (la durée). It shows that transport-mode decisions are not only made in the present, separated from the past and the future, but that the past and the future are part of every such decision. Using the example of the metropolitan area of Brno, Czech Republic, a postsocialist space, we show how differently socialist and postsocialist societies can be temporally normalized. At the same time, contemporary postsocialist mobility decisions are still influenced by socialist time norms—chrononormatives. Our main research question is how everyday mobility decisions between the car and public transport are influenced by the temporal norms of the society. To answer this question, we have employed a mixed methods research design that has been divided into a quantitative analysis of mode choice for individual trips and a qualitative analysis of statements about mode choice. Key findings include the relationship between transport-mode preference and a particular chrononormative. We identify four contexts—time, routing, alcohol, and everyday activity planning—in which the chrononormatives associated with the car and public transport are substitutable. It is on this basis that we introduce intentional automobility.
