Engine Startup!

Hey! This morning I got in the car and booted up like usual. Right away a message popped up saying that since the gasoline engine has not been used, it needed to run a bit for maintenance. It offered to let me defer the maintenance, but I said yes and it started right up. I think the coolest part was, it popped up a little percentage indicator on the speedo and counted up to 100% complete. Lasted about 5 minutes or so. Hearing an engine run should have seemed normal in a car, but it was out of place after 2 weeks of silent running. Then too, when accelerating, the engine speed didn't change... as you would expect when you know the engine doesn't drive the car directly. But still odd when you are used to a conventional gasoline powered car. Fun!
