Without wishing to start a huge sexist debate, it's well known that
females have less well developed spatial awareness. (It's because the
males developed this in order to be successful hunters, which the
females don't generally have to do).

But overall, female cyclists have fewer casualties than male. It's just
with HGVs that they seem to be more at risk.

Which seems to show that while they are more cautious generally, they
don't have the spatial awareness to implement that quite as effectively,
near HGVs.
