I disagree, MOO but I think the driver is important. LE has not stated driver is not a POI, actually LE is out there today taking pictures of tire tracks in front of the home. Kaylee's sister claimed they took an Uber when it turns out they didn't actually take an Uber but were driven home by " private party" We don't know if LE has any idea who the driver was.. or who it was that Kaylee's sister actually spoke with.For those asking so many questions about their ride home, I would think that it may have simply been a different ride-share company.
Although I would also point out that when I have taken Uber/Lyft out at night, I have occasionally taken the driver's contact information to contact at the end of the night. This was a small town. The girls could have had a driver that they used previously that they reached out to direct.
It doesn't sound to me like the driver had anything to do with it. There's video of the girls being dropped off and obviously the driver was identified by the sister and isn't a POI.
