Qatar's the only place I've ever been, or heard of, where women drive worse than men. There was a letter about this in the Gulf Times a few weeks ago. The writer claimed, apparently from experience, that driving instructors didn't even try to tell women learners anything. That fits with my observation that qatari ladies seem to have no concept of lanes. I know the young lads here act as if they don't, but they do really: they just ignore them, which isn't quite the same thing.
A propos Tyrolean's commnet, there was some British research suggesting that using a mobile phone, even a hands-free one, impairs driving as much as having a few drinks. It's NOT like listening to the radio or chatting with a passenger: it's many times more distracting.
