Yeah, it is an important detail. But it'd be nice if we had some more details available, like whether or not it was common to have to override the car. I'd expect that might be common at these crossings, and they may have found a significant issue with something like warning/override fatigue or with the controller interface. It makes sense to stop them until they can figure out with certainty why the operator may have made this mistake.
