Operational Guidance for Map Reroute Distrust

Purpose of This Guide

This guide documents the behavioral sequence known as Map Reroute Distrust: the condition in which a driver follows navigation instructions while simultaneously auditing those instructions against an internal route model that has not been updated since the last time they drove this road.

The guide does not recommend correction. It recommends awareness.

Stage One: The Reroute

Navigation issues a reroute. This happens for any number of reasons: traffic, road closure, a turn missed two exits ago, the app's quiet preference for a different bridge.

The driver notes the reroute. The driver continues following the app. The driver also begins wondering whether the reroute is correct.

These two activities run in parallel.

Stage Two: The Check

One extra check is added. The driver glances at the overview map. The overview map contains information. That information raises a new question.

A second check addresses the new question. The second check reveals that a third check might be warranted.

Stage Three: Parallel Control Systems

The trip now operates under two systems. System One is the navigation app. System Two is the driver's verbal commentary, which disputes System One at approximately forty-second intervals.

System Two has no route data. System Two has strong opinions.

Repetition gives System Two authority. The third time the driver says "this doesn't feel right," passengers begin wondering if the driver knows something the app does not. The driver does not. The driver has made this trip twice.

Stage Four: Arrival

The driver arrives at the destination.

The reroute was correct. It avoided sixteen minutes of traffic. The driver spent eleven of those saved minutes disputing the reroute.

This is acknowledged as a positive outcome.

Stage Five: Precedent

The second instance of Map Reroute Distrust creates a behavioral precedent. The driver now arrives with an established procedure for managing navigation uncertainty. The procedure involves adding uncertainty.

By the third instance, the procedure is policy.

Known Issue

Useful information already exists in all documented cases of Map Reroute Distrust. The useful information does not prevent the extra checks. The checks are not performed to obtain information. They are performed to manage the feeling that information might be missing.

These are different activities.

This guide applies to all navigation contexts. Confidence in arrival does not prevent Map Reroute Distrust. It makes it worse.
