Mobility Mindshift motivates young people to engage with sustainable mobility now and into adulthood — working with local universities, secondary schools, and teachers through speculative design workshops, youth mobility surveys, and a peer ambassador network. Year 1 reached 120 students across four schools, collected 753 survey responses, and established an ambassador network of 20+ members aged 16-55. The biggest insight from Year 1 reframed the project's core challenge: young people already move sustainably. The real challenge is maintaining that behaviour into adulthood and helping them connect mobility choices to broader lifestyle decisions. This shifted the focus from changing current behaviour to building lasting mindsets.
