Well primarily they are for feeding babies it's just that they are associated with sexual attraction probably because they are a sort of symbol of fertility, so I can see why it would be dangerous to drive topless, distracting men and all that...but that doesn't explain why when topless women from the 3rd world are shown on tv no-one gets offended but if it showed a woman in Britain, even in the same situation (ie very poor) her boobs would probably be blurred out...it just doesnt make sense!!
