If you have been here more than 6 months it is illegal to drive on a foreign license, so in that case you got off easy.
Did you say you are pregnant? They love pregnant women here.
My argie husband never pays bribes on principal, but he also has everything in order. He got pulled over the other day and dared the cop to start checking his paper work as he had everything in order. They let him go without checking.
But like you said, it depends if you have time to fight or not.
