For years we've had to listen to it. Despite not being able to park without playing pinball with the back bumper or navigate a country road at anywhere near the speed limit, the fairer sex has constantly reminded men that they are by far the safer drivers.
Well, that oft-mentioned female 'fact' may now have been exposed as wishful thinking following research findings revealed at the University of Michigan.
According to Mail Online, researchers there looked at 6.5 million car accidents which occurred in the US between 1998 and 2007, and found that women were more likely to crash in scenarios involving T junctions, crossroads and slip roads.
The team also found that female-to-female accidents i.e. those that involve two women drivers, made up a far higher proportion of crashes than was expected considering men tend to spend far longer behind the wheel.
The results showed that without a man in sight, the ladies had managed to account for just over 20 per cent of all police-reported incidents. Male-to-male accidents were at 31.9 per cent (lower than expected) with female-to-male at 47.6 per cent.
Dr Michael Sivak, the man responsible for the study, said: 'There are three dominant driver-related factors, including the probability of being at the wrong place at the wrong time, one's own driving skills and the driving skills of the other driver involved.'
Obviously the research is based on American motorists rather than British drivers, but we'd be surprised if the addition of roundabouts to the accident data is likely to bring the female percentage down.
Sorry girls. Science has spoken.
