This writer once lived in the woods in Britain for over three years. Although I still listen to the radio from time to time, I tended to ignore the huge changes happening in real life. I initially heard the alphabet soup term "GPS" while I was still living in America, but always in the context of an army or massive law enforcement or rescue agency. If I heard about a automotive GPS in a radio adverts, I never knew what they were talking about, and failed to care to discover.
