French speed limit

Another thing I noticed during my recent trip north was how good their roads are.From Hendaye to Le Havre i used A10,N10 to poitiers then D roads via le Mans,Belleme and Bernay.From Portsmouth to Yorkshire it seemed half the roads were coned off and the rest would have turned a pint of milk to cheese.Not impressive.What do the French pay as their equivalent of VED?
