This document discusses user experience (UX) considerations for transitions between autonomous and manual driving modes. It argues that level 4 autonomy, where vehicles can drive themselves within a defined "geofence" but require a human driver outside it, provides a pragmatic path forward. Key challenges involve facilitating trust and situational awareness during planned transitions at the geofence boundary, as well as addressing unplanned transitions. The document outlines UX needs for each phase of the transition process to smoothly hand over control between driver and vehicle. The goal is to develop seamless in-vehicle experiences that earn user trust in autonomous technologies.
