A good example of the benefit of familiarizing oneself with the potential taxi route prior to landing. It can be just a brief glance to notice the hazard of the parallel runway with no taxiway in between and therefore to expect an almost immediate hold short line. Then one can plan to exit the landing runway at a fairly slow speed instead of at 60 knots or so.
That doesn’t mean that this scenario is what happened. There seems to be a tendency to let oneself get distracted doing things like after landing flow instead of focusing on taxiing/holding short.
Of course, there is always the simple “we forgot” scenario.
