For "Old Man Le", should I go or stay? How to go and how to stay? The policy of restricting "old man music" on the road has once again attracted attention and discussion. Electric three- and four-wheeled vehicles were often used by middle-aged and elderly people for short-distance transportation because of their convenience and simple procedures.

Some businesses also use "no driver's license, no license plate, low speed, easy to learn" as selling points, resulting in many consumers believing that driving " old man's music" is not subject to traffic regulations.
