Tax on cars is the same or higher in Norway (Except EV’s), and here we love our cars, not our bikes.
If biking is a pleasant experience people will adopt it en masses. If it's a drag on their life then people want to drive instead. Simplez.
Give me a nice bike path network throughout the city and I get rid of my car tomorrow. But those kind of projects are too complex for lazy politicians who seek to fix everything with taxation and call it a day.
