Agree with crumbMC to an extent, but our motorways are absolutety diabolic!! The surfaces are crap, there's not enough of them and there's too many urban on/off ramps, too many trucks (should be limited to inside lane only!) and too many "drones"/jam cars!
Anyway, a year past in June drove from Montreaux to Koln, Autobhan all the way, it was sh1t, 9hrs of M25 type traffic, poor lane discipline (standards are slipping in Germany) and only two lanes for about 98% of the journey.
The best and fastest motorways in Europe are now France's, with Spain a close second, there's a lot to be said for toll roads, although the South of France on the Cote d' Azure is pretty busy and the Costa's motorways are much the same.
The EU subsidies that both these countries have theived over the past 20 years has been put to good use and puts this country firmly in the third world when it comes to any type of road.
