A Slice reader told about being over on the West Side with her husband and entering a Seattle area trip destination in their car's GPS.
Well, the moment they got on I-5 the GPS freaked. Its robo-voice told them to get off the interstate over and over.
Take this exit.
Take this exit NOW. And so on.
They knew those instructions had to be in error. They still had quite a distance to cover. There was no good reason to get off I-5.
Finally, they identified the problem. The GPS computer had somehow been accidentally set to chart the best route for making the trip by bicycle.
