Whenever I walk across a street, I look both ways, and (to the extent possible) visually observe all nearby traffic approaching an intersection. I do this despite the walk signal telling me it's okay to go. Should some inattentive driver decide to come speeding through the intersection and run a red light without stopping, they will absolutely be 100% in the wrong. It doesn't make me any less injured (or any less dead) if I get hit.However, when you say there were things the passenger could have done to prevent the problem, you are placing some of the blame on the passenger.
Point is, it doesn't really matter who's right or who's wrong, or how much they're right or wrong. If there's a way someone can prevent something bad from happening (be it getting hit by a car, or being left on a platform), what's the harm in doing so?
I'd like to think that our goal should be to avoid having bad things happen, rather than being perfectly efficient at assigning blame after the fact.
