A human being is always handy for unexpected situations, and since
BART was one of the first fully automated systems, it had a lot of
problems initially. There may be union requirements for people, too.

The fact that a human operator is aboard a train doesn't mean that the
train can't operate itself in normal service, just as the presence of
pilots aboard an airliner doesn't mean that the airliner cannot fly
itself most of the time.


It can't, fjuccckkkwit.
