Macho men are a liability behind the wheel. Julie Langlois, a doctoral student at the University of Montreal, studied 22 men as they attempted to overtake another vehicle; the men were told that other people had caught up with it in seven minutes. Before taking the test the men also answered a questionnaire - the Auburn Differential Masculinity Inventory - to assess how 'macho' they were. The questionnaire included statements such as "men who cry are weak," and "generally speaking men are more intelligent than women," which they had to agree or disagree with on a scale of 1 to 5. The study found that the more 'macho' a man was the quicker he drove and the more rules he broke and risks he took doing so.
