I guess I could be out of touch. I lived there until 2015, cycling all the time and go back at least once a year but haven't been riding. I just didn't notice much difference especially comparing it to here in Copenhagen where there are bike lanes everywhere, even more than roads. The main focus is bikes and I just haven't felt anything close to that in Oslo. What I mean is that cycling is very popular here and also drinking is very popular here. Not many people think twice about riding their bike home after a few drinks and many do it whilst barely conscious.
