I would like to add my 2c of the difference between German autobahns and UK motorways.
Having lived in the UK for almost 15 years, and now living in Germany for about a year, there are many differences between the two countries driving habits and law enforcement.
1. Germans have great respect for the rules of lane discipline. Unlike the british, they overtake and then move over. Middle lane hogging does happen here quite a bit, but I would say not as much as in the UK.
Their police are out checking speed, drink driving and other bad behaviour on the roads. Not a day goes by not seeing them. They also quite often have road checks only for lorries (checking driving time, weight, certificates and permits for haz goods etc).
2. Road quality is far superior to the UK's motorways. I mean the actual quality of the road/asphalt but smaller roads seems to be worse than in UK with lots of potholes. But again, unlike the UK, I have since the cold winter seen many sections of roads being fixed.
3. Lorries are banned to drive between Sat 2200 Hrs until Sunday 2200 Hrs unless it has a certificate that allows them to drive and transport perishables (ie medicals, food etc). Buses can still drive. This is also law in many other other EU countries and should IMO be the law also in the UK, but as long as the UK motorways and A-roads are small and tiny I guess it is not going to happen as these roads would not be able to cope with the additional lorry traffic on the Monday morning.
Btw, I own a transport company and it works fine with the ban on Sundays.
4. Many sections of the 2 lane autobahns have ban on lorries overtaking. Not just the 3 lane ones. When lorries are banned, it is usually a free speed section.
5. There are still many sections of free speed autobahns in Germany, but as said before, traffic is the main hold up that you may not reach the goal of 155mph and care has to be taken.
I have a saying that however fast you drive in Germany, someone else will still be faster than you!
6. In the year I have been here, I have only seen 3 accidents. One fatal involving a lorry that actually came of the road. In the UK I would see the same number in a day going on the M25!
7. Intersections/junctions between motorways are a disaster here IMO. But newer motorways have a new layout (like an 8).
8. Unlike the british, the germans hardly ever say thanks when you let them out from a junction or let them pass before you etc. In fact, it is very rude not to say thanks I think.
9. Another fact that some british people may have experienced while driving in Germany is the fact how some here can behave when they see a UK regged car.... in my experience mostly with the north around Hamburg, Bremen, Hannover etc. My opinion of this has always been that it has something to do with the two wars + football and as sad as it sounds, it is!
As soon as I got my german car here, I no longer noticed any weird behaviour - even the wife noticed this.
However, when speaking with germans about the UK, the ones that has been there, love it! Except the food ....
Some other OT things about Germany and driving..... insurance costs alot more than in the UK. Fuel is about the same, possible slighly cheaper. Diesel costs less than petrol. You can not have a number plate unless tax & insurance has been paid for. In Germany you insure the car on the VIN and then get the number plates. Your reg doc must be carried at all time, it is your proof that you have insurance and have paid tax and who owns the car, a so called "Zulassungsbescheinigung".
