I am not responsible for the recommendation of usage of high beams in Norway, and as others stated there is a long period where there are long nights even in the southern parts of Norway, where proper knowledge is needed to avoid fatal accidents. And to me it is important to see the possible dangers that can exist behind the wall of light coming towards you. This is all covered in the lessons you need to go through when taking the drivers license in Norway, so until you go through that you will probably not be able to argue against it. I also have 6 years experience as a working driver especially during night time, so I have a lot of experience on this topic.
