I'm really not?
Why would it be any different, there's nothing particularly specialist about driving a car from A to B.
I had a very and I stress, very brief look at some stats. There was an FOI made in 2009, partially answered, as to the amount of male and female drivers.
Unsurprisingly, the amounts run into millions and are slightly in favour of males. I would argue that if males were really so opposed to female drivers as you apparently seem to be saying then we would be seeing carmegeddon on every street corner. We're not are we. You're just being reactionary. This needs to go no further, although undoubtedly you'll take it.
You made a silly statement, you can back down, admit it, no one will think any less of you.
