This morning, I brought my car in for regular service, and decided to wait for it (I wouldn’t have had to, they would happily provide me with a loaner, but this was only going to be a couple of hours, and they have wired & wireless Internet access).  5 minutes before my service manager walked in to tell me my car was ready, I already knew: I happened to be looking at my phone and noticed it had connected to the car!  I’m not sure exactly where the service bays were from where I was, but I suspect it was the other side of the wall, and my car was close enough to establish contact with the phone when they started it to bring it around.  Nice.
