Automated systems elsewhere, such as San Francisco's BART, have been running
for decades.


After checking on the BART system I noticed the following
Quoted:
BART was one of the first US systems of any size to have substantial
automated operations. The trains are computer-controlled via BART's
Operations Control Center (OCC) and headquarters at Lake Merritt and
generally arrive with regular punctuality. Train operators are present
to make announcements, close doors, and operate the train in case of
unforeseen difficulties.

Why, if you're correct, do they have train operators present to make
announcements, close doors, and operate the train in case of
unforeseen difficulties
