that is a really unfair comment! Of all the ladies wearing it I have not seen one who was an aggressive or rude driver. In fact they're all have been very polite and drove well.
Most of the accidents I've seen or heard of were unfortunately caused by men with too much testosterone ;o)
But on a serious note, I think part of the problem is that there're pple from all over the world and all of them drive according to the rules they know from their own countries... which can be quite different for different countries. So a bit of consideration for each other and less aggression should take us further than pointing our fingers at certain nationalities or certain pple ;o)
