When a taxi driver encounters a robbery, he only needs to quietly step on a button next to the brakes. The roof will display the words “Someone is robbed, please call the police†to remind the surrounding people to call the police or help the uniforms. Chongqing Taxi Association said yesterday that it will replace the old-fashioned ceiling lights of 7,600 taxis in the main city from next year, and switch to new ceiling lights with LED display. In addition to the "secret alarm" function, it also has the display "Electric Recruitment". "Extension function."
