That's not different at all. Why would Norwegians be different from other humans? I can confirm that Swedes and danes do this too.
And being of croatian descent I can confirm they do it there too. It's not a cultural thing, it's a human thing to be impatient.
If anything it speaks of the flow of traffic.
Here in Sweden you can often safely cross the street because the entire length of the street has lights that work in a pattern. So there are long gaps in traffic due to lights further up/downstream on the street.
