Just think Stab trim starts misbehaving it can be switched off in seconds and as shown by the Lion Air Flight the aircraft can continue and land - that is what Boeing expected _all_ pilots would do if there was a problem.
Perhaps, just perhaps, the flight crew were being distracted by all the other stuff going on and to them the wheel trim didn't seem to be doing much wrong? Maybe a third pilot should be mandated in future in all non US locations since we all know US pilots are super experienced and knowledgeable!
More seriously I wonder whether Boeing thought through what the cockpit environment would be like for this type of failure with a number of different alarms and failures being indicated by systems.
