What happens if I forget to drop off my brush card when using public transportation in Korea?
Quick answer
The system won't remind you, but it will automatically tell you that you've driven the longest distance. You can continue to use the service without any issues.

Detailed answer
When you're done with your discount, you'll realize what happened. Not every stop will stop. If no one is on the bus and no one is waiting at the station, the driver won't need to default to the stop. Just press the red STOP button next to the stop if you suddenly realize you've been sitting at the station.
