I'm an Amazon driver and we heavily rely on GPS for delivering. We don't just use it for navigating, we also make each delivery inside of a geofence, and the delivery location is recorded and used for future routing. When the GPS says you're a block away from where you are, you're unable to make the delivery without contacting support. I've had days where GPS problems wasted a lot of my time, so I imagine it would be expensive if it happened across an entire region. On the other hand, these kinds of disruptions are already factored into the business model and planned for, so saying it cost an industry X amount of dollars is assuming that the industry was planning for ideal conditions in the first place.
