On another thread TwiceAsNice's phone glitch caused her to put St leafy rather than "At least" and it reminded me of my first encounter with GPS in a friend's car.
Our motorways are called State Highways, followed by a number. On a longish journey, the GPS would insist on guiding us to "Shhhh 16 or Shhhhh 1"
Later, we were told to: 'Turn left into Market Ess Tee"(Market St.) 
The whole journey was hysterical, not least because of the many Maori names the robot had no idea how to say.
Do you have and hilarious GPS mis-spokes?
