The only two things I can recommend about driving in France are:
1. never, ever, drive in Paris. Take the Metro, thank me later
2. if you must drive elsewhere in France, never, ever drive a car with the code „75“ in the number plate. 75 is the code for Paris, and everyone else in France roundly detests Parisians, so if you drive a Parisian-registered car somewhere else in the country, be prepared to get cut-up, insulted, not let out of junctions, spat at, threatened, mocked, blocked-in when parked, if that is, your car is even there when you get back to the car park.
They stopeed the departement as part of the registration years ago. Guess what happened? They protested, as it's part of their indentity, so they all have their 2 digit department codes written under the EU stars.
Paris isn't so bad as it is mostly slow. What fresk the fuck out of you is having right of way to join the periph', the outer ring road has such short slip roads that traffic joining it has priority, so the first time you get on it you have to floor it and just move inot the lane, traffic has to cede to you. You have to remember this as you come up to the nxt junction and let steer clear of the right hand lane to let people on.
