Please excuse the long post.
I have just returned from a 3 week 6 thousand + mile motorbike tour of Northen Europe and Scandinavia. During that time I was able to observe the average driving in 8 countries. I must admit in some cases I was quite surprised about what I observed.
Please note I view myself as a purely average rider/driver. I have too many minor faults in my driving, that I recognise, to currently be any better atm (although I am trying to improve

).
France, Belgium. Holland, Germany and DenmarkMost of my time in these countries was spent on 2/3 lane trunk roads. The flow of traffic on these roads was fairly good even in road works, with a couple of exceptions. The speed limits 110, 120, 130 kmh and unrestricted were fairly well observed, but not absolutely.
The thing that impressed my was the lane disipline. When an overtake was completed the overtaker would in about 99.9% of cases return to the nearside lane, irrespective of need or not to allow following faster vehicles by. Even if this meant they would have to return almost immediately to the outside lane for another overtake once the faster vehicle had passed.
Most of the time a vehicle would be in the nearside lane if no other vehicle were around. Separation distances seemed to be slightly more than I would normally see on UK roads.
SwedenAs with the previous on 2/3 lane trunk roads, very good lane discipline and fairly good but not absolute limit adherence.
On their single lane roads I saw something of a revelation.

When attempting to over take a slower vehicle, it did not matter whether the slower vehicle was going at the limit or below, my indication to overtake would be replied to by an indicator going on and the vehicle in front pulling to the nearside to aid in the overtake

The first few times this happened I was a bit apprehensive, but after a short while it proved to be almost the rule on single lane roads.
FinlandI can not pass to much comment on Finnish drivers as I saw so few of them and was only in the country for a few hours. However the limit adherence was not absolute here.
NorwayWhat a strange county as far as limits were concerned.

In the main most single lane roads are 90 kmh. The are many 80, 70, 60 and even 50 kmh stretches but only around towns and villages. The limits are soon ended once past the the area and mostly the 90 kmh limit resumed.
However when in the more southerly areas the limits seemed to be set more towards 80 or even 70 kmh on roads of better quality for the same density of traffic. This seemed to result in trains of vehicles following at very short separation distances.

Where I would be able to go past many vehicles in short order further north because the gaps were bigger, in the south I would sometimes have to clear two or more vehicles in one go to make similar progress.

Something I rarely did.
Also owing to the almost total adherence to the limits by the Norwegians, in the more southerly areas the speed travel was usually 10 or even 15 kmh below the posted limit because of the trains that built up.

I did see many frustration overtakes by non residents on stretches of road I would be reluctant to attempt something similar.
I very rarely saw the assisted overtake in Norway. When I did it was usually a Swede doing the assistance.
My ConclusionIn the main, outside of towns and cities, the standard of driving is a little better in Northern Europe and Scandinavia baring Norway. Norway seems to be at about our level but with lower traffic densities.
In general the standard of the road surface was much better than we have here. That is from the lightly trafficked north to the much more densely trafficked areas like Hamburg.
Will I be going back? Oh yes. The scenery in Scandinavia is STUNNING. IMO much more so than the Alps or Pyranees

simply because of the contrast of mountain to sea. It is such a shame that I had a camera failure while there otherwise I would have taken an awful lot more pictures.
