Chaos ensued on German roads this week after Google Maps wrongly informed drivers that highways throughout the country were closed during a busy holiday. Many of the apparently closed roads were located near large German cities and metropolitan areas, including Berlin, Dusseldorf and Dortmund.As reported by a locally based journalist for The Guardian, drivers opening Google's navigation app would see a swarm of red dots used to indicate no-go areas, which resulted in people looking for alternative routes that caused traffic pile-ups nationwide. The Guardian also reported that police and local authorities were contacted by people confused (and presumably pretty annoyed) about the supposed standstill.To compound the issue, the Google Maps error coincided with the beginning of Germany's Ascension Day public holiday on May 29, which meant the roads were even busier than usual.
