I pulled into the fueling station the other day, and overheard the attendant ask the driver of the car on the other side of the island to unlock his doors. That particular car has a push-push style gas door, but in order to open it, the car's doors must be unlocked. New one on me.
Our vehicles for the last 15 years have had the indicator, and it points to the correct side. However, my daily driver, a 2004 Malibu Maxx (new model) had the filler on the passenger side. Now that I've traded it for a '16 VW Golf, I find I don't need to break that habit... Both the '12 Canyon and the Sunseeker are on the Driver's side.
I appreciate having the indicator. Like so many others in this thread, I rent vehicles from time to time and it's always good to have some idea of which side to pull into. Now getting the dang door open sometimes is another story.
