Without wishing to be a spoil sport here, this is ridiculous.
The limit on most Norwegian roads is 100kph, so you will nabbed very quickly at any sort of speed above this. I suspect the video has been speeded up a touch.
Actually you are much better taking a Morgan to Norway, you can enjoy at much lower speeds, and you will be welcomed by the population rather than ignored. The Norwegians are very modest folk who do not go in for ostentatious displays of wealth. They do like Morgans though.
The only downside of a Morgan is the rough ride over the road surfaces, especially after winter.
The major downside of Norway is the high price of many goods including alcohol, road fuels, foodstuffs etc. I think the people and the scenery are more than adequate compensation, but I encourage you to make your own minds up and take your Morgan there.
