A serial complainant in Miaoli's Dahu Township triggered a late-night parking blitz, bad news for local drivers and a headache for police.

• Someone called the police hotline repeatedly one night, reporting illegally parked cars across five main streets in the town center.
• Officers wrote more than 50 tickets in three hours, with the caller watching the enforcement the whole time.
• Police suspect the person had been ticketed themselves and turned to reporting everyone else.
• The same pattern hit Toufen City, where a 200-metre stretch of road drew nearly 50 scooter complaints in one night.
• Fines run 900 NT dollars for cars blocking a lane and 600 for scooters, though police mostly just warn drivers between midnight and 6am.

Outlook: Expect more mass reporting and more tickets until towns fix the underlying shortage of legal parking.
