Study Evaluates Meaningful Human Control in Partial Driving Automation

A new study from arXiv (2605.00556) investigates whether partially automated driving systems provide meaningful human control (MHC). Twenty-four drivers completed a simulator study with silent automation failures under two modes: haptic shared control (HSC) and traded control (TC). Researchers derived behavioral metrics from telemetry data and subjective perception scores from post-trial surveys to test hypothesized relations. The study addresses the tension where drivers remain legally responsible but have reduced active control, undermining engagement and sense of agency needed for safe intervention. Empirical methods for evaluating MHC remain underdeveloped, and this research aims to fill that gap.
