[xqhpamfa] Subway door monitors sabotage?

The MBTA Red Line is installing monitors in each station near the front of each train, so the conductor at the front of the train can see all the doors (via cameras) to the other end of the train, and when they are clear, safely close the doors.  They hope to eliminate the additional conductor now at the middle of the train who operates the doors, saving money.

But these monitors seem to malfunctioning often when I notice them.  While it could be incompetence (and likely is, according to the adage), the sinister alternative is malice: monitor-installing employees looking out for, and trying to save or at least prolong for as long as possible, the jobs of their fellow door-operator employees.
