It's MOO that LE is considering many elements related to her intended mode of transportation to work on the 19th, and that any clues they have gathered in this area are some of the information they are witholding from the public for investigative purposes.
Getting to know Mollie... I can't help but think she would make arrangements the night before. So I can't help but think that there are people she phoned or texted to line this up, and in doing so she easily could have mentioned why she needed a ride and her location. Maybe someone said they would get back to her, and then went on to mention to someone else, that Mollie needed a ride. Maybe she even she replied along the lines of gratitude and apologies in advance, in case she didn't answer because she'd be on a 45 minute run. And if there were no calls or texts to coworkers or the likes to catch a ride, I would have to assume she planned to get in touch with her family about a ride. And if for some reason i have to rule out that she intended to call or text Jake about the car, then i have to last assume it was her intention to go there that night or at least jog over in the morning.
I think this is important.
