When I was about six, my mother told me that my grandparents had bought a car that was "automatic". I thought that meant the car could drive itself. I wondered how the car knew where you wanted to go.
Well my grandparents came to pick us up to take us somewhere in their new "automatic" car. After we were all seated, Grandpa got into the driver's seat and proceeded to drive as I had always seen him drive. Or so I thought. I had no idea that there were two kinds of transmissions. I didn't even know what a transmission was.
