In France most of the toll roads are dual carriageways with very smooth tarmac and for the most part, empty, last time I did north to south it was quite expensive but a steady stress free journey, the one good thing they do have on their motorways which we could implement here very easily is a double speed limit depending on the weather, good clear fine weather and it’s 130kph(81mph), bad rainy etc weather and it’s 110kph(68mph) and it works a treat.
