If my memory serves me correctly, it was invented in Netherlands or somewhere in Europe where most people do their vacation travelling in cars. Crossing countries and sometimes not knowing when the next washroom will be. Also, there are many outdoor concerts and very little washrooms - and if you make it to the washroom, I can guarantee you that it's far from being clean. This way, you don't have to sit or even touch the bowl - and if you can't make it to it, you can very simply, lift, remove panties, position and then pee without contracting any disease or being in direct contact with anyone's mess
