There are millions more bad drivers than cyclists, and the drivers are the ones with the lethal weapons! Drivers are very hostile, and bully us on a day-to-day basis. We need patience and courtesy on the roads.
Just choose a EuroVelo route, and you'll have a brilliant time... OR, do what I did years ago, and just cycle via compass --- then you'll discover the truly awful French drivers :) The French have built a brilliant cycle network...but you do have to do some planning ahead of time. The London to Paris route is highly recommended, as is the North Sea route (the roads are perfect...no potholes. & you get to see the myriad of WW2 history in the form of Hitler's Atlantic defences). If you have more time on your hands, do the Danube cycle route. Such an easy route, and takes in some of the most beautiful views in Europe (and some of the best cities!)
I second that, anyone can share their experience. also any advice where to go once in France, some town village nearby?
So how safe it is once you get off the Ferry in France. Are there bike tracks? I don't recall seeing any cyclists on the road on my many crossings?
