Female drivers messing a traffic situation up, get more attention than male drivers doing the same. So subjective perception seems to tell that females are the worse drivers, and on more occaisons. But I am with statistics here, and statistics seem to not support this impression.
Male drivers using car driving as a form of aggressive courtship behaviour and fighting for the chicks' attention, are the bigger problem. Males of any age also are known to will greater risk-taking, in general, not just in car driving and traffic.
Many males seem to think that good driving is an exclusive male domain. Thus this territory gets bitterly defended.
Truth seems to be however that female drivers on average are less aggressive, less conflict-ready drivers. This then gets interpreted by men as weakness, and so the male self-perception stands.
