We spent 2 M in Bretagne, just NW of Quimper and 2 K from the Atlantic ocean. We needed a car, and our French friend helped get us a good deal from the local Super U supermarket chain.
1) French drivers are generally very polite. Very few "hot doggery" in France. Polite accommodation in tight village streets. Watch those "rond-points" though (roundabouts). Most are easy, but the high-traffic ones can be a little challenging.
2) The French idea of "ideal car separation" is 8M. Tail-gaiting is a national sport.
3) French are very sparing in condiments. No mustard on ham sandwiches. We took to carrying our own squeeze bottle of mustard.
4) Wine is very very inexpensive in France. Wonderful selection of all kinds of wine. Most supermarkets would have 200-300 bottles, 80% under 6E.
5) My wife loves sweet white wines. Our favorite - moulleaux. I also liked Entre 2 Mer. For reds, the wines of the Languedoc are my favorite.
6) The cidres of Bretagne are very nice.
7) Supermarkets are driving the village boulangerie/patisserie out of business. Towns often have 1, but used to have 2-3. The markets have 7-8 versions of pate. Bretagne butter is a wonder. You don't get strawberries in January, just in season. The rose onions of Roscoff were delightful.
8) We saw very few police in 2M. I was stopped once for a routine breathalizer. Other than that, no cops at all. We did our best to adhere to speed limits, but French drivers did not. HOWEVER, VERY IMPORTANT - on French roads, you see a "speed check" sign in many places. Be very good about the speed at that point - look for the speed camera. Don't ignore those signs!!
9) We enjoyed Bretagne. We loved the Dordogne. The villages around Carcassone are not interesting. No cafes, no brasseries, just houses.
10) We enjoyed the "enclose parishes" very much - churches with calvaires (outdoor stories of the life of Jesus), ossuaries, arches, walls, and the church. There are many in Bretagne.
11) The Grail church in the Foret de Brociliande was a great stop - Arthur legends with Christian and Pagan stuff.
12) The menhirs at Carnac were great.
