Systems and methods for displaying trajectories for autonomous vehicles
A vehicle includes a computing device configured to detect an object in an external environment via an external sensor. The computing device determines a trajectory for navigation relative the object based on a trust zone. The trust zone is selected based on a trust parameter. The computing device instructs a display device to render a representation of the object and the trajectory relative the object, and determines whether to modify the trust parameter based on feedback data received in response to navigation.
