An important quest for a feminist transport agenda is that policy and practice reflect a diverse set of experiences. This chapter explores how professionals understand sustainable mobility and how their understandings are linked to gendered relations. The analysis shows that professionals use their own experiences of travelling as a source of knowledge. Their understandings of sustainable mobility are built on their own middle-class and family-oriented experiences. Sustainable mobility is thus constructed as something desirable but difficult for families to choose since car offers a flexibility that cycling and public transport don’t. This understanding excludes users who lack resources such as car. The chapter concludes with a suggestion for expanding professionals’ knowledge bases, which can support a future feminist transport agenda.
