On July 29, the news that "smart driving little blue lights are disabled" caused heated debate. In this regard, Zeng Qinglin, general manager of the Yijie Automobile Brand, said in a letter: After receiving this urgent notice, the team took immediate action and implemented it in accordance with national requirements. Zeng Qinglin disclosed two reasons for the ban on small blue lights: "First, there is no uniform standard for the brightness and stroboscopic of blue lights in various households, which affects traffic safety and brings light pollution. The second is that some drivers see vehicles with blue lights, deliberately stuck in other cars to test the limits of intelligent driving, resulting in safety risks. Zeng Qinglin believed that it was a good thing for the state to regulate these chaos. He said," Its original intention is to tell passers-by that ‘the system is driving now’, which is a kind communication. But objectively speaking, the ability to assist driving is uneven. For models with strong intellectual driving ability and high safety limits, the small blue light is an invisible brand promotion; but for models with weak intellectual driving ability, it sometimes becomes a ‘roadblock’, which does bring road safety risks.
