My workplace is situated in a dead end street. It wasn't always so, but several years ago it became a dead end street. I was outside my workplace on the footpath chatting to a workmate when a very large truck with a trailer pulled into the street. 'Mate, my sat nav told me to turn down here. Are there any exits from here?' 'Only down that lane', I replied as I indicated a lane that was clearly too narrow for the large truck.
I had work to do and no intention of guiding a truck reversing out of the street. I bolted. I think I'll hold off on a sat nav for a bit yet. I've heard too many stories. The technology seems a wee bit flawed.
