The best explanation I can come up with is that people assume the GPS has perfect information. Sure, you and I and anyone that&#x27;s used a GPS off the beaten path knows that&#x27;s not true, but that&#x27;s a long way from &quot;everyone&quot;. When you ask yourself, &quot;who would do that?&quot;, the obvious answer is, &quot;someone who was led to believe that a GPS unit is infallible.&quot;
