@@compdude100 most likely yes. It all depends on what the car rental costs are in the country. If they are reasonable I want to rent a car for at least 3-4 days and drive around there.
Great video. I first drove this stretch (downhill from Tyin) in 2016, having joined from the 53 and at the start of your footage, we took what's now the old road around the headland and there's an interesting, old tunnel there with large concrete shelters around the portal. I was back there in September so I took a drive around the old road as the barriers are open. I both filmed the drive and stopped for photos. Going back to Tyin in 2016, there were a lot of earthworks for the E16 taking place at the time as I believe the improvements there required a lot of movement. On arrival next October, I was able to drive the tunnel. The Norwegians know how to build some spectacular mountain roads.
The east of pretty much any country in Europe is drier than the west. It's because of the Gulf Stream, and the reason why London gets less annual than large parts of Europe. To put things into perspective: Marseille, Barcelona and Malta all get around 600 mm per year, whereas London gets 585. The difference is that London gets rain throughout the year, whereas summers in the Mediterranean are hot and dry, with months without rain.
100 without any mid barrier? Norway has among the lowest traffic deaths per capita due to moderate speed limits. To adjust up speed a little and double traffic deaths, there surely is no political agreement on.
Maybe in summer it would be okay in some places, but not everywhere. Also it's about traffic safety and flow, maybe it's 80 kph, but it's steady limit without any frequent slowdowns.
90 is used on a few stretches of ordinary, wide enough 2-lane roads but with very strict requirements. Only very smooth curves so that one can easily keep a constant speed of 90, and no ordinary intersections with other roads. I guess it also has to be at least a few km in length. OTOH, even the narrowest, curviest road in completely rural areas usually has the default speed limit of 80.
Being able to travel longer distances with 80 km/h on cruise control is already quite an improvement for the interior of Norway. No towns, no roundabouts, no tight curves, no narrow sections. The old route of E16 in this area had 60 km/h zones. In the 21st century!
