The Taoyuan City Department of Environmental Protection received the complaint on the night of 22 April 2025. Its Quiet Taoyuan (靜桃) task force immediately set up AI sound camera equipment at the relevant spots. By analyzing the noise data against the complaints, it worked out where and when the car appeared. On 23 April environmental and police officers stopped it near Daxing Road. The car was referred to the motor vehicle office for a modification review. A Noise Control Act fine of up to NT$3,600 and an improvement order are to follow.",

Filed as benefit created or restored as the classifier proposed: the AI located a car that had already been causing the nuisance, and the dated benefit is a one-day enforcement cycle rather than the prevention of a specific future harm. Every report reproduces the Department of Environmental Protection's 29 April statement, with photographs credited to the bureau; the Liberty Times piece carries its own reporter's byline and quotes the director, 顏己喨. The bureau's own press release could not be retrieved (dep.tycg.gov.tw did not respond and tycg.gov.tw sits behind anti-DDoS protection), and the UDN link on the Monitor returns 404. Corrections to the Monitor summary: the fine had not been imposed at the time of reporting; the reports say the car will subsequently be fined under the Noise Control Act (up to NT$3,600) after referral to the motor vehicle office for a modification review. “BMW” appears in the Taoyuan E-News and Guan Media versions; the Liberty Times and Taiwan Hot News say only “white noise car”. The Monitor's “Economic/Property” harm to the general public is the nuisance the car caused, not anything the AI did. Dated to the stop on 23 April 2025; the complaint arrived on the night of 22 April; the Monitor's ID date (29 April) is the press coverage.",
