On Oct. 3, Barry Mattacott, a British marketing specialist living in Vietnam, used Google Maps. The app sent him onto a dirt road in Dang Thuy Tram Commune, Quang Ngai Province.

The road was steep, rocky and muddy. While riding, his motorcycle got a flat tire and became stuck in the mud.

Local residents found Mattacott after he walked for hours. Police officers drove a special vehicle, loaded him and his bike, and took them almost 20 km to a repair shop. After the repair, the police escorted him to a main road.

The police say tourists who do not know the area should not use this road, especially in the rainy season. Mud, landslides and isolation make it dangerous.

Before Mattacott, tourists from Canada, China, South Korea and the United States had also been sent onto the same road by Google Maps.
