<human>:  Why does Google Maps show me a route that is longer than the shortest route?
<bot>: Google Maps is a very complex system. It’s not always possible to calculate the shortest route. Sometimes it’s not even possible to calculate the optimal route. For example, if you’re driving from New York to Los Angeles, the shortest route is probably a straight line. But if you’re driving from New York to San Francisco, the shortest route is probably a curved line.
