Definitely, men here are more murderously aggressive than women. (And when I say "men here" I'm thinking too of some westerners I know.) But the Qatari women really do seem to have even less idea of what lane they should be in than their brothers do. The guys know about lanes, but think that keeping to them is demeaning. The gals are simply unaware of what those white lines mean. A glare and some determined place-keeping might therefore fend off an attacking male, but it'll have no effect on oblivious female.
