Perhaps it's worth hitting "preview route" before pressing the start button when punching an address into your GPS app. Drivers in Denver probably wish the did. In an effort to avoid a crash near the airport on Sunday, Google Maps diverted traffic onto a detour that wasn't quite meant for all those cars. Thanks to recent rain, the dirt road turned muddy, which caused some to become stuck. As more motorists came down the path, they became trapped in a new jam. According to reports, nearly 100 drivers took the app's advice. Ever gotten sent on a strange route thanks to a GPS app? What happened?
