John's receiving an award for his work overseas tonight, and I'm just along for the ride.I'm going along for the ride to my friends' book club meeting later to see if I want to become a member.
Participating but not actively, as in Don't ask me how long this job will take; I'm just along for the ride. This metaphoric term often is preceded by just to emphasize the passive role of the "passenger." [Mid-1900s]
