I was intrigued by:
Until this, I haven’t encountered a mention of a gender preference for uncongested roads. And I don’t get the correlation or causality re “[higher] speed and lower accident rate”. I thought men liked speed more than – or certainly as much as – women might. And don’t we all like lower accident rates?
I do know that congestion robs motorists (and surface-transit users) of family time (among many other things). This could be a reason for a gender-bias on the assumption that women tend to treasure family time more than men do…
…or maybe women are smarter.
