A better example is the AirTrain JFK, which is in New York and is driverless.<p>I don&#x27;t know much about the Paris system, but has unattended operation scaled to the ridership volume of the NYC subway during rush hour?  The problem I foresee is people holding the doors of the train; already a major cause of delays with two staff members in every train.<p>I&#x27;m only familiar with AirTrain, which handles &quot;people getting stuck in the doors&quot; by stopping for an insanely long time at each station, and the Yurikamome in Tokyo, which is tiny compared to the real routes there.
