The lovely voice on my vehicle’s GPS does her best to keep me on the straight and narrow road that is set to my desired destination. She takes me around traffic problems which is nice, but she gets rather huffy if I try to take off and get gas or pull in to a Cracker Barrel! Although she has never used the term ‘recalibrate,’ she is very insistent that I make a U-turn or turn right or left at the next street to point me back in the right direction.
