It’s a lack of social values, or put simply, selfishness. Small things like parking in a restricted area, double parking, many people think “oh, it’s only for a few minutes,” but everyone’s “few minutes” add up and really affect traffic. In the worst cases, drivers park their cars on bends in the road, leading to serious accidents. Aside from irresponsible parking, changing lanes in prohibited areas is another common bad practice; for example, cutting the queue near an intersection or before going on a bridge. It seems most drivers only display road etiquette to pass their driving test. It’s very important that everyone puts those values and correct practices into practice. Strict law enforcement alone can only fix the tip of the problem; we need contributions from every driver.
