Several motorists in Colorado recently found out why GPS can’t always be relied on after Google Maps mistakenly sent them into a muddy mess. According to CNN, the trouble started Sunday when the GPS app took drivers on a detour to avoid a crash near the Denver airport. But the alternate route was far from a timesaver, as it rerouted drivers down a dirt road that had become muddy from the rain. Some of the vehicles weren’t able to make it through the mud, which caused around 100 other drivers to become trapped behind them. Motorist Connie Monsees says she was able to escape muddy mess thanks to her all-wheel drive, but others weren’t so lucky. Monsees says she even had to give two people a ride to the airport so they could catch their flights.
