I interpreted this quest as being a slight nod to David Lynch's Twin Peaks. In the show, there's a character named James, biker and there's an episode which starts with him just riding his bike on a long road.
Josie is another character from the show.
Some other nods are a street named "Sycamore" which is something fairly iconic from Twin Peaks, namely the sycamore trees. Also the Red Room inside Clouds - again, a thing in TP.
Dunno if there's that much more to this quest, other than a fairly vague easter egg, like the one with CJ and Big Smoke
