If it were only robots in the hallways, it wouldn&#x27;t be a hospital.  They did try giving the machines their own pathways.  That&#x27;s what pneumatic tubes were: a fast lane for robotic delivery.  Frankly, for a hospital, pneumatic tubes would seem the far more elegant solution.<p>I guess it boils down to perspective.  The hospital robot is in no hurry.  His life is no better or worse if he is faster or slower.  But a human inside a robot-driven car does care.  He doesn&#x27;t see the overall traffic efficiencies, and even if he did he wouldn&#x27;t take much notice.  All he cares about is getting to the destination asap.  So it is a different speed decision than the robot.
