Delta Fleet AI is a speculative VR demo exploring the hidden human labor behind autonomous mobility systems. Set in a future where autonomous vehicles rely on remote human "RoadRunners"to manage edge cases, users engage in high-stakes scenarios including route selection, manual driving, and obstacle disambiguation. Framed as a corporate onboarding simulation, the experience critiques the myth of full autonomy and exposes the cognitive and emotional demands placed on undervalued human operators. Built for MetaQuest 3, the project showcases VR's potential for provocative speculative design, inviting reflection on automation, labor, and the ethics of human-autonomy teaming.
