In Denmark they've actually increased the speed limit on some roads by 10km/h in the name of reducing the number of accidents. After trials on the sections of road concerned they have finally realised that the nominated speed limit has little effect on drivers, most of whom tend to drive at a speed which they feel comfortable with according to the configuration of the road system.
They are of the opinion that lowering the speed limit below what is practical for the sections involved is actually more dangerous, as impatient drivers often overtake traffic which they consider to be driving too slow.
I know things are different in France, Geoff. I was once ambushed by three Gendarmes who literally jumped out of a hedge in the Bocage district of Normandie. They thought I was just about to fail to come to a complete halt at a "Stop" sign, but were disappointed as I stood on the brakes when I caught sight of them, and one of them stumbled into the front of my car, which was fortunately then stationary. When they realised I was an "etranger" all they were interested in was if I had those deflectors on my headlamps to dip them to the right. Fortunately I had them fitted, and I got off with a small dent in the front offside of my car caused by a Gendarmes's boot.
Thanks for the warning. I was driving in mainland Greece earlier this year where it's just a case of survival of the fittest. You never stop until you've made absolutely sure that the driver of the vehicle behind you is not on their phone, and you just blast your horn at everything and everybody until they get out of your way. Speed limits are for learners and old people, and most of the drivers in Halkidiki are Macedonians, Serbians, Romanians, and Bulgarians, who couldn't care less what the Greek traffic laws are. You get fined 750 Euros if you ride a moped or motorcycle without a crash helmet, but you win 1500 Euros if you see anybody actually wearing a crash helmet. Most older Greeks have never passed a driving test, but just bribed the local licensing officials to obtain a licence. That practice has now been outlawed, same as riding a motorcycle without a helmet!
