This chapter focuses on the subject conceptualisations within mobilities research. It highlights the role of automobility in constituting prototypically modern subjectivity in order to strengthen the argument of the co-constitution of social formations and mobile subjectivities. The co-constitution and co-emergence of socio-spatial order and subjectification have been elaborated by numerous mobilities scholars in relation to automobility. Mobility, infrastructures and spaces are being constructed and made meaningful through a range of symbols, representations and discourses. The topographical separation of working and dwelling that makes car driving and thus car owning necessary for large parts of the workforce in Western societies did not just naturally happen but is itself at the same time the cause and effect of the modern spreading of car mobility. Other mobile subjects pedestrians, public traffic users, cyclists, passengers although co-products and derivatives of automobility are of lower degree of generalisation and recognition.
