I would recommend public transport rather than renting as car. When using public transportation, I encountered local people who are friendlier than those who consistently work with tourist. My first trip to France we did not rent a car, we used the train, taxi cabs, and walked. If you are traveling to Burgundy, you may consider renting a bicycle.
We traveled to Provence last year; we hiked from Bed & Breakfast from along the Randonne in the countryside. We visited small villages and towns with very little tourist significance. We had several very pleasant encounters with people in the French countryside; we wondered why many Americans think the French are unfriendly when we were having drastically the opposite experience.
Bon Voyage
