”Why are modern navigation systems like this?” Hundreds of cars stuck on farm roads for hours in South Korea

It has been alleged that hundreds of cars trying to get home following directions from a popular navigation app in South Korea ended up stranded on farm roads for several hours.
On the 18th, a thread on social media said, "Hundreds of cars had been parked in a line on a farm road in Asan City, Chungcheongnam-do since the previous afternoon.
One SNS user wrote, "The navigation system told me it would be quicker to take the farm road, so I came here, but other cars were also on the farm road, so I was stuck in front of and behind them.
"I tried to go quickly, but I ended up locked in a prison," he said, adding that it took him more than three hours to get out of the five kilometers.
Another user wrote, "A line of cars that have been fooled (by the navigation system)," and "It's unusual to see hundreds of cars lined up on a farm road that has been stuck there for an hour."
