Metro Community Connector ???

Can someone please explain or even guess who exactly these community connector shuttles are intended to serve? A person can only travel within their tiny zones, and shuttle service generally ends at about 5pm (sometimes 7pm). It doesn't really have the ability to accommodate walkers and other aids for seniors. I thought it may be a decent option for those out drinking, but the hours don't accommodate that. Who exactly is traveling within those tiny zones, and can deal with an unknown and unpredictable wait time (you can't schedule, it's first come first serve). They look cool, and maybe that is the benefit, it helps Metro's name, but who exactly is it intended to serve? Any thoughts?
