Belgium is the only other country apart from the UK I can think of where I've experienced the same feeling of being 'off road' whilst actually being on the motorway network. Even they don't seem to have the same levels of traffic of UK roads south of roughly Preston /Newcastle though.
French roads in general are a joy to drive on, German autobahns too, if you can put up with the occasional scare as something flies past at Mach 1.
