Purely out of curiosity...
I was sat in the car with my DD at the services, watching the world go by, when she asked me: "Why is it always the man who drives?".
I looked, and she was right - every car with both men and women in it, a man was at the wheel! I didn't really know what to say to her...
So, when you're in a car with a member of the opposite sex, who's driving and why?
YABU - the woman
YANBU - the man
