In July last year, Jiang obtained his driver's license and soon after purchased his first car. As a novice driver, he was somewhat confident in his driving skills. Encouraged by a friend, he spent over 400 yuan on an "electronic dog" to help him navigate the roads. Initially, the device seemed useful, alerting him to road monitoring systems several meters in advance. However, his confidence in the device soon waned as he encountered its limitations.
An "electronic dog" is a device designed to alert drivers to speed cameras, traffic monitoring systems, and other road hazards. These devices are popular among private car owners for their affordability and perceived utility. According to a salesperson interviewed by a reporter, the cost of an electronic dog is often offset by the savings from avoiding traffic fines.
A search on Taobao for "electronic dog" yields over 7,178 items, with some shops reporting weekly sales of up to 235 units. One buyer noted that the device alerted them to nearby traffic posts and police cars several hundred meters in advance. Sales staff claim that electronic dogs can detect both fixed signals and GPS signals from mobile police cars, a feature not available in other navigation systems.
Despite their popularity, electronic dogs are not without their flaws. Jiang, who initially found the device useful, encountered issues during a trip to Jinan. Despite the electronic dog's repeated speed warnings, he still received a traffic violation. Similarly, Master Li, a taxi driver, found the device unreliable. During a 40-kilometer trip on the Jining Jinxiang 105 national highway, the electronic dog issued six alerts, three of which were false alarms for gas stations rather than speed monitoring points.
The use of electronic dogs is a contentious issue. According to Zhuya Feng from the Jining City traffic police, the devices have a dual role in providing tips and evading regulations. The newly revised "Road Traffic Safety Law" does not explicitly address the installation, use, or sale of electronic dogs, leading to significant debate.
The traffic police department frequently upgrades road monitoring systems, but these updates are not synchronized with electronic dog systems, leading to potential misinformation. Additionally, factors like weather and radio waves can affect the accuracy of these devices. The traffic police department advises drivers to obey traffic laws and not rely solely on electronic dogs for safety.
While electronic dogs offer some benefits, their limitations and potential risks cannot be ignored. Drivers should prioritize obeying traffic laws and driving safely rather than relying solely on these devices. The evolving landscape of road monitoring systems and the inherent inaccuracies of electronic dogs make them a supplementary tool at best, rather than a reliable solution for road safety.
