Do you live in the PNW? If not, you may not be familiar with the drizzly rain we have so much. Me personally, even if my house was ten minutes from the park and ride, I would still drive just because I don't want to start my work day off wet from the rain! Even with an umbrella, the bottoms of your pants get wet, your shoes get wet, and then you're starting off your commute and work day wet and cold. I do not find it strange at all that she would drive to the park and ride, despite it being walkable from her home. Also, I would be creeped out walking in the dark and the rain, so from a safety standpoint, I would drive for that reason too. I think especially in the PNW, people often drive instead of walk simply because of rain.
