I think the OP needs to be aware that France does things the wrong way round.
France joins the tiny minority represented in part by Germany, Serbia, Denmark, Greece, Lithuania, the USA, Spain, Algeria, Luxemburg, Romania and countless others in insisting on deliberately standing in the way of the correct traffic system.
They drive on the right side, which is to say the wrong side. I mean the incorrect side.
They also cycle on that side and drive their lorries on it. No traffic at all uses the correct side, which just seems lazy to me.
This might have given the OP the impression that things were more chaotic than they are.
Also I've noticed, having lived there for a few months, that all the driving in France is done by the passenger, not the driver.
This is because (for reasons I cannot fathom) the driver has no controls in front of him. These are all mounted in front of the passenger.
Why anyone would want the front-seat passenger to drive them around is anyone's guess, but like all those countries listed above and many more, France seems to think this a good idea.
This is, frankly, typical of a country like France. They insist on having a French word for everything, and even when they use the proper (English) word they pronounce it in some strange, foreign accent. For example: France, Paris, train, table, impossible.
So, OP... Look out over there. It can be jolly, jolly tricky and if you get yourself into a scrape, people will feign ignorance of English however loudly and slowly you speak and however much you provide helpful actions to get your point across.
Don't say I didn't warn you!
I knew a snail once, who lived in France. He drove a sports car with a big letter 'S' on the bonnet and roared around the lanes of Tarn & Garonne in it. I never did work out why he did that.
