From memory there was a study made a while ago regarding what the strengths are in men and women.
Men scored highest in geometric shapes, distances, logical thinking, mechanical and such.
Women scored highest in creativity, art, and such.
I just remember the geometric shapes and distances one because that is 110% driving - knowing your car size, other distances and shapes on the road.
The claim that women are better drivers by insurance companies is unfounded - but the truth behind the original statement is that women are less prone to be hoons on the road. God knows I've seen enough to cause accidents though.
