I recommend against driving in Norway, the UK, New Zealand, much of Greece...

Rock Creek parkway is pretty much flat and hardly twisty. The lanes have markings and a standard width. There are no cliffs and it has guard rails.

On driving difficulty it gets a 2 out of 10. Very easy. Almost every road outside a city in Norway is on a cliff with constant blind turns and you need to know where the corners of your car are to inches to not hit the trucks that come around corners. There are no markings in the middle of the roads and there are reindeer, free ranging sheep and moose.

Essentially people need to be instructed how to drive better I guess. Norway takes it seriously. They enforce speeding harshly and alcohol even more so. Having driven there I saw why. The US road system is way too easy which lets people drive fast and badly.

Wide lanes are what make people drive fast that is well known if you want people to drive slowly you have to make lanes much narrower.
