Having traveled quite a bit – and read about it – I have come to terms with the fact that cars in some countries drive on the right side of the road and in others on the left.

What startled me however was a sign in my neighborhood that announces a sudden change from right to the left hand, or as more appropriately called here English hand – mão inglesa.

Is it to check if drivers are awake? Or to see how much confusion one can possibly create? And will we ever know?
