CNN - Technology isn't always foolproof, as about 100 Colorado drivers learned when Google Maps offered them a supposedly quick way out of a traffic jam.
A crash on Peña Boulevard, a road leading to Denver International Airport, prompted the app to take drivers on a detour on Sunday.
But it was too good to be true.
The alternate route took drivers down a dirt road that rain had turned into a muddy mess, and cars started sliding around.
Some vehicles couldn't make it through the mud, and about 100 others became trapped behind them.
