I would think this is very unusual, French roads are usually free moving, smoother, repaired better and cleaner. I wish we had their network instead of all our outdated, cobbled together bits of road which are constantly under repair or under construction with seemingly no completion date.
Not to mention, wonderful roadside picnic areas, truck stops that sell proper food at reasonable prices and the open space provided by a country five times the size of our own, with a similar sized population.
