@Samurai f someone asked a question that doesn’t make complete sense its good to use common sense to guess what they are meaning.
Ok, I’ll ask you one with as much information as you provided. You guess and give a valid answer.
I am in Australia (7,686,850 km2) – what is the cheapest way for me to get to my home?
You don’t know where I live, and you don’t know where I am at the moment (I travel a lot).
As for your original query, carry no ID and get yourself arrested for a misdemeanor then only speak French to any authorities. With a little bit (or a lot) of luck they’ll deport you to France.
