Another potential issue with the 6000 series trains?

Well this is disturbing:

No Passenger Train 714-6080 reported to #WMATA ROCC @ 11/12/20 10:52PM that the train failed to respond to braking commands while passing through Rockville station and remained in motion to almost Twinbrook

YOLO

Reads to me like operator error on top of train malfunction.

WMATA has had controller handle malfunctions on cars in other series in the past.
