I did not overlook it; and yes, it was obvious to me,
when I posted. I implied as much, when I wrote:

"Small groups are the best protection for both sexes."

It seems like you are trying to misunderstand.

The motorist has been covered on so many threads;
it is one instance, that I will not re-hash.

In a survival situation, an exceptional women would be
a bonus; one who could take on navigational duties, while
in the front passenger seat, might be a life saver.

Beware of the biased-sample problem, examples follow:

"At the track meet, I saw 20 women faster than you..."
"I know 10 Karate women who could kick your ass..."
"When I was in the army..."

There can also be a biased reporter problem: he sees what
he wants to see; remembers what he wants; ignores other
evidence.
